Sunken Roman statue at Baiae, Italy As humans spread across continents and populations exploded, trade between civilizations became more frequent. Coastal settlements allowed larger ships to come and go, increasing trade and boosting the local economy, with many port towns being built as a way to access rare goods and wealth. have. But the riverbank is not always a safe place to settle down. Saeftinghe Swamp, Netherlands A swamp in the Netherlands known as the Sinking Lands of Saeftinghe, the area was once a prosperous village. In the 13th century, humans drained the swamp so that they could build on the fertile land; they also built dykes around the reclaimed land to protect it from flooding. Much of the land around Saeftinghe was lost in the flood of 1570. Dutch soldiers fighting in the war for independence from the Spaniards were forced to destroy the last dyke barrier. while defending Antwerp, allowing Scheldt’s waters to take over the town. However, a local legend tells a slightly different story, blaming the flood of 1570 on the rampage of a mermaid held captive by the townspeople. Today, the settlement is buried under layers of sand and clay, although bricks have been recovered that may have belonged to a monastery due to the floods. Caribbean Pirate Paradise The Caribbean pirate’s paradise of Port Royal, Jamaica was known as “the worst city on Earth”, before a devastating earthquake and subsequent tsunami pushed two-thirds of the town under waves. The violent shaking liquefied the sand beneath about 2,000 brick buildings, which were displaced and appeared to flow into the sea. Of the town’s estimated 6,500 inhabitants at the time, 2,000 are believed to have perished in the earthquake and tsunami. More than 3,000 people died from injury and disease afterward, according to UNESCO. Salt beach in Germany This place was once a busy trading port. Rungholt’s exact location – long regarded as a legend – remains unclear, although artifacts and evidence of tillage found in the Wadden Sea suggest its existence. a trading port. The flood of Saint Marcellus, also known as the “Great Drowning of Men”, is believed to be the culprit behind the town’s disappearance. High tides caused by extratropical cyclones ravaged the coasts of northern Germany and Denmark, killing thousands. Atlit Yam, Israel The oldest settlement ever discovered in the Mediterranean with interesting rock structures such as Scotland’s Stonehenge. This Neolithic village lies 8 to 12 meters deep under the Mediterranean Sea, hidden for more than 8,000 years until marine archaeologist Ehud Galili discovered it while surveying sand for shipwrecks in 2014. 1984. It is now considered one of the oldest underwater settlements ever discovered. Careful excavations have uncovered rectangular houses with fireplaces and the remains of a dry rock well. One of the most interesting finds is a megalithic structure – similar to Scotland’s Stonehenge – built around a stream, made of seven giant stones weighing around 600 kg each. Burial sites and human remains have also been excavated. One study suggested that a tsunami may have caused the settlement to be abandoned. Baiae, Italy Baiae was once a spa town in Rome that was famous for its debauchery. Underground pressure in the area causes the land to rise and fall, and much of its ancient history is now below sea level. Notably, the underwater remains of the Pisonian Mansion and the statue of Nymphaeum decorated by Emperor Claudius were sunk deep into the water. In addition, several prominent Romans visited the resort town during its heyday, including Julius Caesar, emperors Hadrian and Septimius Severus, generals Gnaeus Pompeius Magnus (Pompey the Great) and Gaius Marius and politician Lucius Licinius Lucullus. Underwater city for over 3,000 years in Greece Hy The city of Pavlopetri, Greece has been submerged for more than 3,000 years. The ruins of Pavlopetri were discovered in 1967, and analyzes of building materials and pottery shards show them to be about 5,000 years old. The town remained above ground for 2,000 years before it could be sunk by earthquakes. The layout of the town has been perfectly preserved 4 meters under the waves, with streets, buildings and tombs eroded over time but still visible. At least 15 buildings have been identified. Thonis-Heracleion, Egypt A statue of a Nile god found underwater is important evidence of the area’s existence. Located northwest of Alexandria on the Nile Delta, Thonis-Heracleion was a famous trading port before earthquakes weakened the land and dragged it under salt water. The area is full of artifacts, but the colossal 6-ton statue of the Nile god Hapi is one of the most important finds among the ruins.

To have a feng shui living room, we need to clear the space. The living room is one of the common areas of the house, so it needs to have a well-ventilated space. You can burn herbs, diffuse essential oils, or ring a bell to create a living room canopy. 2. Create an open space One super easy way to clean a living room is to open all the windows in the room for at least 9 minutes. Nine is the most auspicious number in feng shui. This will help the old energy to leave and make room for new energy. Don’t forget to clean the windows. Use a non-toxic cleaner or use vinegar and water. 3. Arrange furniture Many people leave too much stuff in the living room. The living room needs to be rearranged. Keep the necessary items and discard the unnecessary items. 4. Use the bagua map You need to apply the bagua map to see which of the nine areas corresponds to the location of your living room. You can then use the properties of this area to attract wealth to the living room. The easiest way is to rely on the color of that area. For example, if the living room is located in an auspicious area, you can use gray for good luck. If the living room is located in the two bagua areas, the more fortune there is. 5. Balance the five elements The Five Elements is a Taoist system that uses the cycles of nature to help balance our health and happiness. The five elements include earth, metal, water, wood, and fire. The easiest way to bring good feng shui into the living room is to include one of those five elements. Here are the characteristics of shapes and colors according to the theory of the five elements: – Earth has brown, orange, yellow and square, flat shapes. – Needles are white, gray, metallic and spherical, round shape. – Thuy has black, dark blue color and wavy, wavy shapes. – Wood is blue, green, and rectangular, column-shaped. – Fire is red and triangular in shape. 6. Choose the color of the living room Feng shui colors and symbols are related to the Bagua as well as the five elements. So colors are used in feng shui to enhance or support specific areas of your life. Choose feng shui colors and find the energy that suits your living room. Then you can choose the paint color, furniture, decoration or other accessories that match the living room. It is important to listen to your intuition. If you are attracted to a particular color, choose it. If a color doesn’t work for you, pay attention to it. 7. Create space for each person Since the living room is a common space in the house, you should weigh the furniture carefully. Make sure there is a comfortable seat for each family member. Everyone in the house feels welcome and close. For people to talk and interact, arrange chairs across from each other. If possible, avoid having chairs facing each other. 8. Decorate the living room with green plants Trees bring life energy into the house. It’s a simple way to design a feng shui living room. Do not forget to plant trees with enough light, space and water. 9. Art paintings When decorating a living room with art, keep three things in mind: – Choose pictures with meaningful colors or five elements. For example, a red painting symbolizes passion, recognition, and vision. – If possible, avoid emotional artwork or pictures that carry your memories. – Do not hang art too low, otherwise it will reduce the positive energy in the house and lead to depression. Hang art paintings at the appropriate height for the space. *This information is only for illustration purpose .

This photo was taken by reporter Tran Quang Minh in early 1974 at the war zone D (the Southeast). Rightmost are Ly Van Tich, followed by Nguyen Sy Thuy, Pham Cao Phong (passed away in August 2020), Vu Xuan Ban, Kim Son. In the last month of the year 1974, three reporters believed: Vu Xuan Ban was at the same class GP.10 (later Head of the editorial board in the country), Nguyen Minh Nhut (post-liberation was Editor-in-Chief of Dong Nai Newspaper) and I left based on the Propaganda Committee of the Party Committee of Ba Ria-Long Khanh province, they returned to the Propaganda Board of the Southeastern Party Committee located at the Ma Da base in Bien Hoa (Dong Nai now). Two photojournalists Vu Kim Son and Tran Quang Minh continue to stay locally to work. The road we will have to pass outside through the old forests of the East must also pass two roads: Highway 1, the section near the town of Long Khanh, Highway 20 to Da Lat, the section passing Dinh Quan district. Bien Hoa province and Dong Nai river, in the rainy season, often red water overflows the two banks, flowing quickly to the sea. This is the road where we went from the base of the “General Commune” to the TTXGP, but when it was in the dry season, the streams in the dry forest were bare and the small rivers with clear water could walk through. easy and gentle Dong Nai river, drifting quietly. The three reporters we joined with the delegation consisted of cadres from “R” back to the locality to work again, some of the provincial officials went to “R” for training. Communication led the delegation to follow the predetermined route suitable for both operation time and convenient living (safe, close to water sources …). On preparing to cross National Highway 1, the team will take the group to stop at the intersection station in the forest of Bao Binh commune (Long Khanh town), which is about 2 hours’ walk from National Highway 1. The weather was cloudy, indicating a possible end of season rain. The whole group stretching, hanging hammocks under the trees waiting for darkness will pass the highway as planned. Near the end of the afternoon, the rain began to grow heavy and gradually grew bigger and longer. In the south, the rains are usually short, but sometimes there are also prolonged rains. And this is the case. Heavy and prolonged rain, water from the high mounds flowed into a stream around the intersection station, forming a pool of muddy water. From many layers of trees, rain water poured onto the roof rose, wobbling and splashing the roof. The traffic company announced that it might pass the highway sooner, so it is suggested that everyone prepare dinner early to be ready for operation. Although the rain had not stopped yet, we quickly finished the cooking and finished our dinner, prepared everything so that we could march as soon as the communication orders were ordered. Darkness gradually covered the wet forest, the whole group set out to wade through the muddy gutter, to the edge of the forest, across the fields to plant crops and fruit trees of the people on the outskirts of Long Khanh town. It would be better to march in the rain, especially passing places like national highways, near the post, because the rain water will erase all the marks of passers-by. The whole group quietly followed the intersection to cross the fields to the highway. No one is allowed to use a flashlight because it is not far from Long Khanh town, on the top of Chua chan mountain (Ray river?) There are enemy posts. If detecting a suspicion of “Viet Cong”, they will shelling violently. However, sometimes from the top of the mountain, the enemy fired flares to help the whole crew operate more easily (with the contact they traveled many times, so they belonged to the pathway). Then the whole group also came to the side of the road. After observing and clearing landmines, the traffic force signaled to the crew to cross the highway while the rain had not stopped enough to erase all of our footprints from the field into muddy fields. The group quickly slipped into the dark in the fields north of the highway. It seemed that everything was safe and smooth, but in front of us, the stretch of Ray River passed through the field in the blinding light of flares kept by the enemy, the water overflowed on the fields. The day when the leader of the TTXPP disseminated the plan for GP.10 to the provinces, I would like to go to the Southeastern provinces because I could not swim (swim), so if I went to the Mekong Delta, the canals were crowded. will not be convenient for travel. Leaders agree. However, it is not foreseen: floods, people who can swim, can cope, and floods, sometimes even people who can swim are difficult to overcome. We were wondering, worrying about the situation due to heavy rain, extending this stretch of Ray River, when we went from “R” to the province, the water is just above knee high, now not only rising, but also fast flowing and breaking the tops of trees on both sides of the bank. Mr. Thang told the team to wait for him to find out which part of the river is convenient to hug (a compact, lightweight, waterproof backpack) and swim along the water to the other bank. Moments later, he turned and led everyone back up a bit, in the dim light of the flares, the stretch of river that the party would cross was quite empty on both sides, sparse trees. All were prepared to put their clothes (including underwear because there were no women in the group) to hold, tie and prepare to cross the river. The rain has stopped, the river is still rushing. I honestly told my associates and members of the crew that I could not swim. One opinion raised was that I took the umbrella rope (using a hammock) of many people to stretch it across the river so that I could follow it to the other bank. That’s an initiative, but it takes a lot of parachute ropes to get across the river. Mr. Bang, Mr. Nhut, many brothers in the group and I had to open the rope to reconnect the hammock. Mr. Ban looked for a tree stump on the south bank, tied the rope around his umbrella and swam diagonally down the river with his team members to the other side, looking for a firm stump that was tied tightly. I carried the cuff on my back as a float, and at the same time followed the parachute rope stretched across the fast flowing water and safely crossed the shore. Mr. Xuan Lan had to swim back to the other side to remove the parachute rope (the hammock rope of many people) and then swim again to quickly join the union. Mr. Bang had to swim back and forth three times in this river to help me. The enemy’s artillery from the top of the mountain was still firing and guarding, helping the party to quickly cross the fields to plant fruit trees soaked in rainwater to the old forest. Entering the depths of the forest when the enemy flares no longer light our way, people used flashlights to shine. The light of the light, the sound of footsteps rustling the nocturnal animals, the sound of deer and deer (mink) echoes in the distance. Late at night, we arrived at the intersection of the small stream, and everyone took advantage of the stretch, hammock and slept to regain their health for the next march the next day despite being able to walk during the day in the forest.

Images of hundreds of people without masks crowded together at Santa Monica pier and watching street performances on Venice’s walkway have raised fears that California spring break could go out of control. This case happened in the city of Miami Beach, Florida. On March 20, Mr. Dan Gelber, mayor of Miami Beach, declared a state of emergency because of the huge wave of tourists flocking here. After more than a year spending more time at home than on the street, many people are eager to party in the sun when summer comes. However, wearing a mask and exercising social distance makes the fun even more fading. Covid-19 vaccination is underway as planned. According to the The Guardian about 50% of adults in the City of Los Angeles have received at least one shot. However, local health authorities warn that it is too early for the public to lose their guard. Barbara Ferrer, Los Angeles’ public health director, advises people during this time not to rush to travel and gather large numbers of people. However, some leaders want to lift pandemic restrictions to restart the economy as soon as possible. Many people flock to famous places in California. Photo: The Guardian. Several theme parks reopened this week. Outdoor bars and bowling alley will be allowed to resume operations in Los Angeles on April 5. “Every indicator we are monitoring locally is on the right track. Everything is very good, ”Eric Garcetti, mayor of Los Angeles, said during a press conference on 29/3. In it he just mentioned briefly about the things that need to be done for spring break. With the current situation, Rochelle Walensky, director of the Center for Disease Control and Prevention (CDC), has a contrary opinion with Mr. Garcetti. New infections are on the rise again, she said. The country is in danger of losing its advantage in the fight against the Covid-19 epidemic when a new variant of the SARS-CoV-2 virus spreads rapidly. Over the weekend, 100,000 people visited the famous pier in Santa Monica without any anti-epidemic measures. Santa Monica city leaders are planning to limit the number of people on the pier by not accepting visitors before 3 hours of closing. They also run the program “Health Ambassadors”, recruiting people to remind visitors to wear masks.

As recorded, late on the night of April 23, after a long heavy rain, a series of areas in Mui Ne ward (Phan Thiet city) and Hoa Thang commune (Bac Binh district, Binh Thuan province) had a sand spill incident. , many serious places, causing traffic jams for many hours. Sand floods made the land of Doc Mo (Hoa Thang commune, Bac Binh district, Binh Thuan province) torn apart. In which, the area most affected is route 716 (the Doc Ma section, Hoa Thang commune, Bac Binh district). According to local people, at the time of the heavy rain, sand and water from the hillside collapsed onto Road 716, causing serious congestion, a series of vehicles could not move. Due to the large amount of sand and water pouring down, the land on the road 716 was torn apart, forming a trench nearly 20 meters deep, hundreds of meters long running straight to the sea. By the morning of April 24, vehicles were able to pass through the 716 road area of ​​Bac Binh district By the morning of April 24, the amount of sand and water that had drifted along this trench poured straight into the sea so the means of transport were able to move normally. Also on the coastal road in Mui Ne ward (Phan Thiet city), a series of places similar sand spill phenomenon occurs, causing traffic to be affected. In the area before the real estate project Apec Mandala Wyndham Mui Ne, the overflowing sand covered a section of the road As observed, in the area in front of real estate projects Sunny Villa and Apec Mandala Wyndham Mui Ne, sand overflowed to cover a section of the road. Currently, these project owners are sending manpower and means to clean up the consequences. In particular, also on the night of April 23, at the GoldSand Hill Villa real estate project, the phenomenon of sand overflowing continued to make it difficult for many vehicles to travel. Before that, late at night on April 20, after a heavy rain, there was a serious sand spillage phenomenon, causing many vehicles to be buried, many restaurants and people’s houses were affected. Also on the night of April 23, in the face of complicated heavy rains, there was a risk of sand spillage, Mr. Nguyen Van Phong, Vice Chairman of Binh Thuan Provincial People’s Committee and the delegation checked and suggested Stakeholders take measures to ensure safety, prevent landslides, overflowing sand, affecting people’s lives. Late April 23rd, at GoldSand Hill Villa real estate project, the phenomenon of sand overflowed, making many vehicles difficult to pass by. Along with that, after the sand spill incident at the GoldSand Hill Villa real estate project, the Chairman of Binh Thuan Provincial People’s Committee issued a document to direct the concerned departments to completely resolve the situation. Binh Thuan Provincial People’s Committee assigns the Department of Construction to coordinate with relevant units to organize a physical inspection of the project area, compare all design documents, construction permits, construction items, verify cause of landslides, sand; review all project documents, request the project owner to immediately remove the recovered sand from the project, to avoid similar landslides when the rainy season is coming. In the coming rainy season, if the authorities and real estate developers do not have solutions to prevent sand spills, the problems will likely continue to occur.

According to the photo provider, these models are “dried” by the Toyota dealer in Dong Hoi (Quang Binh) and sold to customers as new cars. This information made many users concerned and expressed concerns about the quality of flooded vehicles.

Information of a Toyota dealer selling a flooded car was posted on social networks on April 14. Photo: TT.

Facebook account Nguyen Hoa asked a question on the Dong Hoi city community about how to check for flooded cars. In addition, this user also wondered how flooded the Toyota cars in the photo were flooded at the time.

Zing Contact the Toyota Quang Binh showroom deputy director to verify the incident. He said that during the 2020 flood in the locality, some dealers’ vehicles were recorded affected by the disaster.

Specifically, the representative of Toyota Quang Binh confirmed that 6 cars were wet with water, the rest were not damaged. For vehicles with problems, the dealer has asked for support from technical experts of Toyota Vietnam to handle and overcome. After that, this volume of vehicles was disclosed the flooded treatment information and sold to a taxi business.

Meanwhile, a representative of Toyota Vietnam said he would check and reply as soon as possible Zing ask questions about the incident.

According to auto expert Nguyen Son, flooded cars can affect the quality of use. Water entering the engine compartment and cockpit can damage the electrical system and interior details. In addition, prolonged immersion may cause corrosion and rust in the chassis and mechanical components.

According to the National Meteorological Agency, at present, the trend of temperature is gradually turning to a neutral state. With this development, the hurricane season this year is expected to come more wanted than every year, but need to be careful of strong storms; the rainy season can come early with extreme phenomena; risk occurs drought and local water shortage in Central and Central Highlands.

More information with VietnamPlus Electronic Newspaper reporter on the afternoon of April 15, Mr. Nguyen Van Huong, Head of Climate Forecast Department, National Hydrometeorological Forecast Center, said that from now until about May, it is unlikely to export storms and tropical depressions in the South China Sea. However, in the following months, storms and tropical depressions will begin to operate and increase in frequency, lasting until the end of 2021.

Specifically, in the period from June to July, storms and tropical depressions are likely to begin operating in the North East Sea and gradually increase the frequency, likely to affect the Northern region. and North Central region from August to September; affect provinces in Central and South Central from September to the end of this year.

“It is forecasted that this year there will be about 10-13 storms operating in the South China Sea, of which about half will affect the mainland. In which, strong storms will occur from September to October, “Huong said.

Also according to Mr. Huong, normally in the first half of the season (from June to September), tropical low pressure will concentrate in the North and the South China Sea, potentially affecting the North and North Central regions. ; in the second half of the season (from September to November), it will focus on the Middle and South East Sea, affecting the North Central Coast and returning to the South.

With the storm trend mentioned above, localities need to be careful of strong storms with complicated movements and cause strong winds at sea in months. stormy rainy season year 2021.

Regarding the trend of the rainy season, Mr. Huong said that this year’s rainy season is likely to come early in the Central Highlands and the South, from about the second half of April to the first half of May, thunderstorms and whirlwinds may occur. , hail, strong wind. In the last 6 months of 2021, rainfall tends to increase nationwide.

During the dry season months, the flow volume on most of the common rivers is approximately 15-40% lower than the average of many years in the same period, some rivers are 50% lower. Risk of drought and local water shortage in Central and Central Highlands.

In the flood season in 2021, the annual flood peak on the main rivers in the North, North Central region and Central Highlands is usually around 1-2 and above fluctuation 2; rivers in Yen Bai and Ninh Binh, from Quang Binh to Binh Thuan fluctuate 2-3, some rivers fluctuate 3.

The annual flood peak in the watershed of the Mekong River on Tien River in Tan Chau and Hau River in Chau Doc fluctuates 1-2, lower than the average flood peak of many years from 0.1-0.3m. In the dry season 2020-2021, salinity intrusion in the Mekong River Delta is at a high level but not as serious as the dry season in 2019-2020. Since May, saline intrusion in the Mekong Delta tends to decrease gradually.

The period of moderate and large floods in the North is likely to concentrate more in the second half of the flood season. On small rivers and streams, in the upstream areas, big floods, flash floods, and landslides are likely to occur; Inundation in cities and urban areas continues to be at risk from local heavy rains in the flood season months.

Before the weather trend mentioned above, the representative of Forecast Center Hydrometeorology The country said that the Ministry of Natural Resources and Environment will continue to direct hydro-meteorological forecasting and warning units, continuously monitoring, monitoring and updating daily on the website of the Ministry of Natural Resources. and Environment, General Department of Meteorology and Hydrology, soon provide detailed forecast information and warnings to functional agencies, media agencies and the people to prevent and avoid ../.

“Trees soaked in water for 20 days cannot survive,” said landscape planner Ngo Anh Dao, who has planted dull forests along the 650m long shore of Triem Tay and neighboring Cam Kim commune since 2018. Sad is sad, she said, but this is the law of nature.

The cork tree is the body

According to TS. Ngo Anh Dao is “a pioneer tree and a sacrifice for the posterior generation behind.” As a result, although the number of poor trees is only 1/3, the riverbank of Trem Tay village does not erode like in the previous years when floods came.

This poor forest is the outermost layer of an ecological soft embankment coping with landslide. Anh Dao put it to the test at her farm An Nhien after the historic flood in 2017 seeped 12ha of the riverbank area. Before the embankment was constructed, each time the flood came, the banks of the Trem Tay River would recede more than ten meters deep and many villagers determined that they would have to leave sooner or later.

The ecological soft embankment model is the result of many years of observation and research by TS. Anh Dao goes downstream of Thu Bon river. She does not consider this as a new invention but simply a process of restoring indigenous ecosystems.

“This is a very sensitive and fragile area,” said the female landscape planner, when she was under pressure from the water pouring in from the Truong Son mountain range, and the pressure from waves and storms. Just comparing the map of Thu Bon river basin from 1984 with the present, anyone can recognize the appearance, swelling and disappearance of floating dunes. If more than 30 years ago, there were four large and small sand dunes in front of Trem Tay, over time, the side of the mudslide, now they have formed a large dune deviating to the north, causing the flow from upstream to crash into the bank of Trem Tay village and the neighboring Cam Kim commune. Therefore, every time the flood comes, the Trem Tay bank will slide and the other sand dune bank accretes.

The villagers of Trem Tay seem to be too familiar with this harsh law of nature. At the age of 54, Pham Duoc had to move his house twice despite being born and raised in this village. His first home was at the head of the village but by the age of twenty, he was forced to move to the middle of the village. In 2009, the commune authorities urged him to continue to move, but because of “comfortable housing, a garden, a chicken”, he decided to stay. However, after the historic flood in 2017, when the water flooded to 1.6 meters deep, he got scared and decided to demolish the house, sell the land and move to his current home at the end of the village.

“I wanted to build a house to leave for the children, so I accepted it,” he was told. Each time like that, he “is not sad” because “has to accept it.”

Also because of the desire to keep the village and have a passion for planting trees, this builder began to work as TS’s farm housekeeper. Anh Dao from 2016 on a piece of land at the end of the village abandoned because some people have retreated inland like Mr. Can. Others, especially the young, have quit farming because their rice land is either no longer available or salty, and go to work on tourism in Hoi An or Da Nang.

On this wasteland, Mr. Can and other workers have built wooden houses with modern designs, combining the high structure of stilt houses with indigenous materials such as bamboo and grass. The houses are mixed with nursery gardens and research of diversity of plants.

Standing from the house overlooking the river bank is a bamboo forest that villagers planted in the 1980s to prevent floods. “Thanks to this bamboo forest, when the flood comes, the flow will decrease”, he is explained. “Like when water runs through that basket.”

In front of the bamboo forest, along the riverbank is the ecological embankment.

Use “soft” against “hard”

Different from the commonly applied concrete hard revetment in Vietnam, the soft revetment does not resist the destruction of waves and floods but backs and accepts it – more similar to the village motto of living with floods. This 200 years old.

“The current popular philosophy is that people are fighting against nature, conquering nature with hard solutions and ignoring the understanding of coastal ecosystems, the access between water and land”, PhD. Mr. Dao analyzed. “Thinking like conquering nature, using it hard against the power of nature will be terrible because its destructive power will be even greater.”

Principle TS. Cherry mentioned that the law is immutable in physics: punching a wall with your hand will always hurt more if you punch the mattress with the same force. And given the increasing intensity and destructive power of storms and floods due to the effects of climate change, new coping measures are becoming more and more imperative to minimize damage from dike breaks.

In the design of the ecological embankment, the cork tree is TS. Cherry brought back to plant from Quang Tri, is the outer layer of the buffer protecting the village shore. The roots of this plant are of two types. The main root is poked straight down, possibly up to ten meters deep. The secondary roots, also known as lung roots, are precipitated when immature, soft and swaying with the waves. When the tree grows, this lung root hardens, protrudes from the mud about 60-80cm, very hard. Therefore, cork trees have the ability to accumulate mud, hold soil, and reduce the destructive power of underground waves.

Next to the cork layer is a layer of grass, including native grasses such as hammer grass, grass with bald roots that can be up to 3m deep below the ground, next to the pangasius is a two-leafed tree, the roots are even deeper. tens of meters. These are easy-to-live, fast-growing plants with good soil holding capacity.

The last layer is a row of casuarina trees planted from 2017 that are 8m high. In addition to the ability to hold soil, the height and softness of the conifers help to both block waves and windbreak.

These three layers together create a green vegetation reinforced with bamboo biological “lock” layers to support soil retention in the early years when the layers are young, the roots are not deep enough.

With the initial results achieved, TS. Anh Dao is confident that the philosophy behind this model is the right direction for the sensitive downstream areas that are suffering from both natural disasters and natural disasters. The flood discharge of dozens of hydroelectricity upstream; exploitation of sand in the river bed; monoculture agriculture, improper exploitation of groundwater, causing subsidence; along with tourism development, regardless of the fragility of the ground here, all contribute to increasing the risk of landslides in the area, he explained.

Natural balance

Realizing the initial efficiency of the project, in addition to the affordable price – the construction cost of 1 meter of ecological embankment is only 1/5 of the cost of building the concrete embankment – Hoi An government plans to extend 900m of longitudinal embankment. According to the territory of Phuoc Thang village in the neighboring Cam Kim commune, where after the flood in 2017, the bank fell 50 meters deep into the mainland.

However, the ecological embankment is not without its risks. “An embankment requires a tree to develop to a certain extent to be effective,” said Nguyen The Hung, vice president of Hoi An city. This is a fact to consider when choosing the time to start planting trees for ecological embankments because according to the experience of the Hoi An people, every three to five years a big flood will repeat and the poor forest also needs that many years. to be able to cope with floods.

The most obvious evidence is the initial failures in the construction of ecological embankments by TS. Cherry. In fact, the horticultural forest she planted in 2018 was the second test after the failure of 2017, when the historic flood hit and killed the immature cork trees that were only one year old.

Pham Duoc, born and raised in the village of Trem Tay, had to move his house due to the impact of floods and landslides. Photo taken on January 26, 2121 in Trem Tay village (Dien Phuong, Dien Ban district, Quang Nam province). Photo: Yen Duong

Therefore, each ecological embankment requires a deep understanding of the local soil and climate. Invited by the authorities of Dak Nong and Dak Lak to study the replication of an ecological embankment model for the Krong No riverbank, which is suffering from severe landslides, PhD. Anh Dao cannot carry the whole model from An Nhien. The key thing that does not change is the principle of using measures of “soft, back and forth” instead of “forward and conquer”.

Post-flood cleaning in An Nhien continues after Tet. Meanwhile, the poor forest has begun to show signs of revitalization. “Maybe I will leave it alone, the cork tree will grow back on its own, or I will plant more, depending on the budget”. Anh Dao said.

What is important according to the doctor is the long-term perspective. Once the embankment ecosystem is returned to its natural equilibrium, other social and economic benefits will follow.

Since the ecological embankment, shrimp, fish, birds, wild ducks, many insects have created a new source of livelihood for the village. Each spring, “so many birds can not sleep at night,” he shared. The green embankment on the transparent river also contributes to attracting more tourists to visit this ancient village.
