receiving streams is called a waters, into which (granted) an introduction can take place from landing on water (waste water, drainage water). To the use a water-legal arrangement must at the responsible authority (e.g. Water authority) to be requested. Receiving streams are falsely called also Vorflut.
natural receiving streams are open running waters, which take up water from other waters, from groundwater bodies or discharge systems.
Every now and then is stated that larger receiving streams can be used in addition, an inundation, as for instance the Elbe flood 2002 to take the point. The success depends substantially on at which time of the receiving streams and which filling conditions he is flooded before had. Some experts doubtone more than marginal note effectiveness of this level point adjustment.
In principle for it systems would be suitable for the increase of the efficiency of the waters system or for the improvement of the flood support. Enlastungsgerinne, tide hollows make cutting of Hochwasserspitzen by the increase for the removal ability possible of the Hauptgerinnes by means of the creation of further coagulate to partial derivativethe flood wave.Polder or other support areas can be flooded more or less purposefully. Thus a retention (a support) of a part of the flood wave with the goal the point of the flood develops to caps. The emptying of these support areas takes place, if again sufficient capacity is in the waters net given.
