Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. [1] The term "at flood stage" is commonly used to describe the point at which this occurs.
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 ...
Urban flooding is the inundation of land or property in cities or other built environment, caused by rainfall or coastal storm surges overwhelming the capacity of drainage systems, such as storm sewers. Urban flooding can occur regardless of whether or not affected communities are located within designated floodplains or near any body of water. [1]
Floods are caused by many factors or a combination of any of these generally prolonged heavy rainfall (locally concentrated or throughout a catchment area), highly accelerated snowmelt, severe winds over water, unusual high tides, tsunamis, or failure of dams, levees, retention ponds, or other structures that retained the water. Flooding can be ...
As emergency services continue to search for those still missing in Spain, many are questioning what caused the devastating flash flooding which has killed at least 217 people.
Several characteristics of the water cycle have the potential to cause sudden (abrupt) changes of the water cycle. [7]: 1148 The definition for "abrupt change" is: a regional to global scale change in the climate system that happens more quickly than it has in the past, indicating that the climate response is not linear.
After pummelling other Mediterranean countries, the powerful Storm Daniel swept into Libya at the weekend, unleashing record amounts of rain as it made landfall. The rain dumped by the storm ...
The Zanclean flood caused a major change in the environment of the Mediterranean basin; the continental "Lago Mare" facies was replaced by Zanclean deep sea deposits. [7] The flood may have affected global climate, considering that the much smaller flood triggered when Lake Agassiz drained did result in a cold period. [50]
