The next step is to decide which system elements are to be used to map the sub-catchments, depending on the problem and the data basis. Alongside the system element sub-basin, which brings the load into the system via a precipitation-runoff simulation, the system element point source can feed the outflow from the sub-catchment directly into the system via a hydrograph. The latter is of course only possible if a hydrograph is available. Then it is the solution using the fewest computational resources, which in addition (with good quality of the input data) also illustrates the actual outflow behavior in a realistic manner. If, however, for example, a forecast is to be calculated with changed land use conditions or if the hydrograph is not long enough, it is advisable to use the system element sub-basin. In Talsim-NG the selection of the system element for sub-catchments can also vary from sub-catchment to sub-catchment.
