While the damage caused by many forms of disasters are commonly immediate, floods are often longer events; due to the sheer amount of water left behind in their wake.

Commonly caused by flash floods and torrential rain, inhabited areas near rivers and bodies of water are most susceptible to floods.

Particularly strong floods can sweep away buildings, and property damage and crop destruction are the most common after-effects. The flood waters can also become contaminated and cause illness or disease.

Satellite data can prove very useful in the analysis and monitoring of flood events. It can be used to provide historical reference of the area before the flood, as well as determining the extent and location of flood waters after the flood, aiding in the relief and recovery efforts.
