Example for the system boundaries of a study area

The system boundaries of the water resources system are to be set in a way that all loads and processes important for the problem are represented in the model. This also includes all system states relevant for control. Often, the first definition of system boundaries 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 boundaries 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.
