Ways to help reduce the dangers of floods?

One of the best ways to help reduce the dangers of flood is to make new laws which restrict human activity, such as building, in a floodplain. Some areas of the country will not allow construction in areas which have flooded over the last 100 years. This law is called the "100 floodplain law". Another way to reduce the dangers of flood is to reduce stream side erosion. If the banks of rivers erode, it is easier for the banks to wash out and flood surrounding areas. Another way to control the dangers of floods is to check dikes and levies designed to keep flood water out. Levy and dike failure were responsible for much of the catastrophe in the great New Orleans flood. Finally, flood dangers can be reduced by careful water control at reservoirs and damns.


Why does buliding on flood plains cause floods?

Building on flood plains doesn't really cause floods. A flood plain is somewhere that is prone to being flooded. So it is not a good idea to build anything on it, as sooner or later it is going to get flooded. Some building work may result in water being diverted and if it is not planned properly, flooding may occur. That is down to bad planning. Flooding is a natural occurrence, caused by excessive amounts of water. Building in the wrong place or doing some building that affects the natural flow of water can result in places being flooded.
