Experience against flooding in the city

Cambodia

According to Phnom Penh Post, the historic flood in November 2011 caused severe flooding in many areas in Siem Reap province. Under the direction of the Cambodian Ministry of Water Resources and Meteorology, the provincial government built a dam in the Ta Soum temple to prevent flooding. At the same time, local people were also instructed to build higher houses, remake village roads and build small dams.

Later, despite the heavy and continuous rains, Siem Reap was no longer flooded, as rainwater could escape quickly into the nearby Tonle Sap Lake.

Thailand

The 2011 flood also caused the biggest loss in 50 years in Thailand, killing more than 675 people and injuring millions. Irin reported that in 2012, the Thai government spent $ 3.9 billion to build water pipes and water channels, allowing 1,500 million cubic meters of water to flow through every second. In addition, Thailand also focuses on improving embankment, sluice gates and canal construction. Under the plan, US $ 2 billion will be used to convert 3,240 million square meters of farmland along the Chao Phraya River north of Bangkok into an area to prevent floods that could hold 10 billion cubic meters of water.

To prevent flooding, Japan built the world's largest floodwaters in Saitama City, near Tokyo, in 1992. According to Weird Asia News, the project includes five large concrete vertical wells. 65m high, 32m wide, connected by a 6.4km tunnel system, located 50m deep from the ground. The architects also built 59 reinforced concrete columns to support the weight of the ceiling. Flood water is sucked into wells and discharged into Eldo River.

Brother

London's capital is easily flooded, especially when strong storms make the Thames river water rise. However, the people of London can be assured thanks to the water barrier on the Thames called the Thames Barrier, which began operating in 1982. Skift reported that the project is half a kilometer long, including 10 high steel gates. equal to 5-storey building. According to the British Environmental Agency, this flood protection system will survive until 2070.
