There are several types of urban flooding, each with a different cause. City planners distinguish pluvial flooding (flooding caused by heavy rain), fluvial flooding (caused by a nearby river overflowing its banks), or coastal flooding (often caused by storm surges). Urban flooding is a hazard to both the population and infrastructure.
Flash floods can cause rapid soil erosion. [14] Much of the Nile delta sedimentation may come from flash flooding in the desert areas that drain into the Nile River. [15] However, flash floods of short duration produce relatively little bedrock erosion or channel widening, having their greatest impact from sedimentation on the floodplain. [16]
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non ...

The region is particularly at risk of flash flooding – due to its hard ground and vulnerability to the “cold drop” – but its infrastructure has been unable to protect its residents.
Floods in the United States (2000–present) is a list of flood events which were of significant impact to the country during the 21st century, since 2000. Floods are generally caused by excessive rainfall, excessive snowmelt, storm surge from hurricanes, and dam failure.
what caused the flood? The rain dumped by the storm filled a normally dry riverbed, or wadi, in the hills south of Derna. The pressure was too much for two dams built to protect the city from floods.
