Area 1

Title

The runoff coefficient is the quotient of the part of a precipitation event that comes directly to the runoff (also called effective rainfall) and the total rainfall. The runoff coefficient can be entered manually or selected from the menu and must be between 0 and 1. The DWA regulations recommend the following runoff coefficients depending on the surface condition:

Title

According to DWA M153, the burden of precipitation discharges is defined by so-called load points. The load points B are made up of the air load L and the wing load F.The following classes are distinguished for the air load L according to M153:
