Nachricht im Original (Einzugsgebiet)

Die Verdunstung wirkt sich in zweifacher Weise auf die Abflussbildung aus. Zum einen sind die Anfangsbedingungen im Einzugsgebiet (Benetzung und Muldenfüllung auf der Oberfläche sowie eingeschränkt auch die Bodenfeuchte bei durchlässigen Flächen) ein Resultat des vor dem betrachteten Niederschlagsereignis stattfindenden Verdunstungsgeschehens, zum anderen wird der zu berechnende abflusswirksame Niederschlag um den Betrag der momentanen Verdunstungsrate geschmälert.

Evaporation has a double effect on runoff generation. On the one hand, the initial conditions in the catchment area (interception and depression storage on the surface as well as to a limited degree the soil moisture of permeable areas) are a result of the evaporation taking place before the considered precipitation event. On the other hand, the current runoff-effective precipitation is affected by the amount of the current evaporation rate. The potential (energetically possible) evaporation VP varies in time and place and is very difficult to calculate exactly. Using evaluated measurements of 20 stations, the mean values of which are presented in the following histogram, the following compensation function was determined /BRANDT, 1979/.

	Evaporation has a double effect on ~~the formation of~~ runoff. On the one hand, the initial conditions in the catchment area (~~wetting~~ and ~~trough filling~~ on the surface as well as ~~limiting~~ soil moisture on permeable ~~surfaces~~) are a result of the evaporation taking place before the considered precipitation event. On the other hand, the precipitation ~~to be calculated, which affects runoff,~~ is ~~reduced~~ by the amount of the current evaporation rate. The potential (energetically possible) evaporation VP ~~is very different~~ in time and place and is ~~hardly accessible for an exact calculation~~. ~~From~~ evaluated measurements of 20 stations, mean values of ~~these stations~~ are presented as histogram~~.
