[[Datei:Eingrenzung_des_Untersuchungsgebietes.png|thumb|Example for the delimitation of a study area]]The delimitation of the water management system has to be carried out in such a way that all loads and processes important for the problem can be represented in the model, including all system states relevant for control. Often the first delimitation is based on the boundaries of a hydrological catchment area (e.g. determined in a GIS) and is then possibly extended if processes/states outside the area influence the system or if information outside the catchment area is to be used, e.g. for calibration. The system delimitation can also change due to the system elements that are determined after the subdivision into system elements. If subcatchment areas are mapped e.g. as external inflows by [[Special:MyLanguage/Einleitung|point source]], the system boundaries become smaller accordingly. | [[Datei:Eingrenzung_des_Untersuchungsgebietes.png|thumb|Example for the delimitation of a study area]]The delimitation of the water management system has to be carried out in such a way that all loads and processes important for the problem can be represented in the model, including all system states relevant for control.

The delimitation of the water management system has to be carried out in such a way that all loads and processes important for the problem can be represented in the model, including all system states relevant for control. Often the first delimitation is based on the boundaries of a hydrological catchment area (e.g. determined in a GIS) and is then possibly extended if processes/states outside the area influence the system or if information outside the catchment area is to be used, e.g. for calibration. The system delimitation can also change due to the system elements that are determined after the subdivision into system elements. If subcatchment areas are mapped e.g. as external inflows by point source, the system boundaries become smaller accordingly.
After the system delimitation is done, the water resources system can be divided into system elements.
