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. The following compensation function was determined /BRANDT, 1979/.
