The streaming indicates in Hydrologie the phenomenon of water run-off on the surface of the grounds. He is opposed to the phenomenon Infiltration.
The streaming is one of the engines of the erosion: the water which runs out involves with it more or less large particles according to the quantity of water moving and the slope, which can have an abrasive effect on the ground subjected to the streaming.
The streaming is also a phenomenon taken into account during urban installation , because the generalization of the waterproofed grounds (Route S, automobile parking, built-up areas, etc) increases the streaming with depend on the infiltration, which can lead to violent Crue S and increases the risks of saturation of the collectors of water and Inondation downstream.
The streaming is a factor of aggravation of pollution related to the Agriculture: the Manure and other pesticides are involved towards the rivers, then towards the sea, instead of remaining on the place of spreading.
