The data to be entered in the topography section is typically determined in a GIS. The area of the sub-basin is crucial for the amount of generated runoff, since the precipitation is processed into the precipitation-runoff-model as precipitation height [mm] and, therefore, has to be scaled with the area.
The degree of imperviousness dictates the percentage of impervious area in the sub-basin and describes the proportion that runs off as urban surface runoff. The urban surface runoff is calculated separately from the remaining natural surface runoff and retained in a separate storage cascade. The discharge sequence assignment can also be used to assign this runoff to a different outflow element. The values for longest flowpath and maximum and minimum elevation are used to automatically calculate the surface runoff retention constants.
