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.
Flood risk management includes mitigating and preparing for flooding disasters, analyzing risk, and providing a risk analysis system to mitigate the negative impacts caused by flooding. [ 61 ] Flooding and flood risk are especially important with more extreme weather and sea level rise caused by climate change as more areas will be effected by ...
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]
According to the National Weather Service, a flood is an overflow of water onto normally dry land, usually caused by rainfall, storm surges, debris jams in waterways, or breaks in levees, dams or ...

This long-duration river flooding caused hundreds of levees failures, 50 fatalities and an estimated $15 billion in damages. While the worst of the flooding occurred in the summer of 1993, impacts ...
Economic loss risk for six natural disasters: tropical cyclones, droughts, earthquakes, floods, landslides, and volcanoes. A natural disaster is the very harmful impact on a society or community after a natural hazard event.
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 ...
