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 antecedent conditions 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.
