Floods are the phenomenon of water in rivers, lakes flooded a land. Floods can also be used to indicate flooding due to tides, sea level rise due to storms. Floods can occur when water in a river or lake overflows or breaks a dyke causing water to enter the dike protected areas. While the size of the lake or areas of water may vary with the season depending on the precipitation or snow melting, it does not mean that floods unless flooding spills out endangered lands such as villages and towns. city ??or other settlement.

Floods can occur when river water levels rise due to floods that overwhelm and destroy buildings and houses along the river. Floods can be mitigated by moving people away from the river, but economic and livelihood activities are often associated with rivers. As a result, people continue to settle in areas where there is a high risk of flood damage, as the value of living near the river is higher than the cost of flood forecasting periodically.
