Refrlaction

Flooding is a temporary overflowing of water onto land that is normally dry. Flooding may happen with only a few inches of water, or it may cover a house to the rooftop. There are many possible causes of floods including heavy rain or snowmelt, coastal storms and storm surge, waterway overflow from being blocked with debris or ice, or overflow of levees, dams, or waste water systems, Flooding can occur slowly over many days or happen very quickly with little or no warning.

Possible ways to mitigate risk to floods hazard.

Channel modifications- can enlarge cross-sectional area and thus create a situation where a higher stage is necessary before flooding. In other words by enlarging the cross-sectional area, higher discharge can be held within the channel.

Dams - Dams can be used to hold water back so that discharge downstream can be regulated at a desired rate.

Levees, Dikes, and Floodwalls-These are structures built along side the channel to increase the stage at which stream floods.
