Systemelementsdaten/en: Unterschied zwischen den Versionen

Once the system elements have been created in the system plan, the calculation method for individual system elements is selected and appropriate parameters are inserted. This is done in the data sheet for each respective system element.

The determination of parameters can vary greatly. Some are known (e.g. diameter of a circular pipe), others require extensive preliminary work in a GIS (e.g. the division of a subcatchment using soil maps, land use maps, determining gradients from a DTM in areas reacting hydrologically similar and finally elementary areas).

Even if parameters are not known and they are the objective of a calibration, a first estimate must be appointed as an inital value for the calibration.

-The determination of the characteristics and parameters is very different. Some are known (e.g. pipe diameter of a circular channel), others require extensive preliminary work in a GIS (e.g. the subdivision of a subcatchment area using soil maps, land use maps and the gradient determined from the DEM into hydrologically similarly reacting areas, the elementary areas).
