A flood (in Old English flod, a word common to Teutonic languages; compare German Flut, Dutch vloed from the same root as is seen in flow, float) is an overflow of water, an expanse of water submerging land, a deluge. In the sense of "flowing water", the word is applied to the inflow of the tide, as opposed to the outflow or "ebb". The Flood, the great Universal Deluge of myth and perhaps of history is treated at Deluge in mythology.
Main causes
The main cause of floods is not any geological or weather, but the distribution of human populations near water. Since Mesopotamia, man has built cities and communities by the sea or rivers for the access to cheap and quick transportation and access to food sources and trade. However fertile soil in a river delta is subject to regular inundation from normal variation in precipitation.
Floods from the sea can cause overflow or overtopping of flood-defences like dikes as well as flattening of dunes or buffs. Land behind the coastal defence may be inundated or experience damage. Floods from sea may be caused by heavy storm (storm surge), high tide, a tsunami or a combination thereoff. As most urban communities are located near the coast, this is a major threat around the world.
