What does RAINPLANER® calculate for swale infiltration?

Dimensioning of the required swale volume or alternatively the required swale depth for all relevant duration levels and return periods – iteratively and standard-compliant.

Calculation Methods

Swale Volume – DWA-A 138-1 / DWA-A 138

Iterative calculation with rainfall intensities for freely selectable duration levels and return periods, optionally according to DWA-A 138-1 (10/2024) or DWA-A 138 (04/2005).

Swale Depth – alternative design procedure

Alternative design procedure for determining the required swale depth, optionally according to DWA-A 138-1 (10/2024) or DWA-A 138 (04/2005).

ATV-A 138 (Reinhold rainfall intensity)

Calculation with the location-specific rainfall intensity according to Reinhold (r(D=15min,n=1)) in accordance with ATV-A 138.
