The water balance equation for a soil layer is solved on the basis of the area-wise linear representation of the process functions infiltration, current evaporation (evaporation + transpiration), percolation, interflow and capillary suction, which influence soil moisture. The input variable for evaporation and transpiration is determined from the potential evaporation. The equation to be solved is:
