right The data to be entered in the Topography section is normally determined from a GIS. The area of the catchment area is decisive for the amount of runoff that is generated in this catchment area, because the precipitation as precipitation height is included in the NA calculation and is therefore still scaled with the area. The degree of sealing determines the proportion of sealed area in the total area and describes the proportion that runs off as urban surface runoff. The urban surface runoff is separated from the remaining natural surface runoff berechnet and retained in a separate Speicherkaskade. The Ablaufzuordnung can also be used to assign it to a different discharge element. The input for longest flow distance and maximum and minimum height are used for the automatic calculation of the Retentionskonstanten des Oberflächenabflusses.
