If a [math]\displaystyle{ \Psi }[/math] value is given, the remaining part of the precipitation after covering the initial losses (wetting and depression losses) is converted to runoff by multplying with [math]\displaystyle{ \Psi }[/math], independent of the history and the characteristics of the rainfall event (amount, intensity, duration). If possible, this approach should be avoided, since the process of runoff formation is greatly simplified.
