What are the measures to prevent flood ?
Today, there are many ways to help prevent and control floods. Flood-control dams have been constructed throughout history across rivers. Dikes and levees are built alongside rivers to keep them from overflowing during periods of high water. Canals are also used to help drain off extra water. Streams and rivers can be diverted to avoid highly populated areas. Regulation of floodplain development and urbanization would reduce flood losses. Prevention of soil erosion also helps control flooding, which is why it’s a good idea to plant lots of trees, treat slopes and grads, and create reservoirs to catch sediment and debris. The bottomlands, bogs, marshes, and swamps are very valuable in preventing and controlling floods. The wetlands act like giant sponges that soak up huge amounts of water and let it run off slowly. When these areas are filled in and built over, floods are more likely to occur.
