Select Subcatchment

This item enables the selection of a subcatchment for a simulation, i.e. by selecting a stretch by clicking. However, the new simulation run will only work on all upstream stretches.

The active scenario view is raised to the full extent and the cursor shape changes. If the active scenario already contains simulation results, users will be asked to delete the data because they will not be related to the new catchment subset.

For identification purposes the selected stretch is coloured red and the end of the simulation network is marked with a red point.

This feature reduces the simulation time if only a smaller subcatchment is of interest. It should be noted that on the other hand some of the analysis functions will not work properly on a subcatchment data set.
