Kristina IsbergIf you already have subbasins delineated for your model in a shapefile you can choose to import these to WHIST. You can choose to import with already given routing information or generate the routing from a topography database of your choice (but still following the WHIST requirements). When the data has been imported you can treat them in the same way as if they had been created in WHIST from start.
The shapefile imported must have the same coordinate system as the WHIST database (i.e. the topograpy data, DEM, DIR, ACC/UPA) you want to use, i.e. your first decision is to prepare the topography data and check that it is accepted in WHIST.
- Go to HYDRO/import.
- use "replace all previous subbasins"
- use "max flow accumulation pourpoint generation method
- browse for your shapefile under Input file/folder
- Choose the column for the subbasin ID´s.
- Choose (if available) the column for the next downstream subbasin.
- Click on Import
If you did NOT have any routing described it should have been set during the import. If this is not the case, select all subbasin and use the tool under HYDRO /Edit 2/Autolink. Two new windows will appear but you just need one of them.
Autolink settings for setting routing and pourpoints according to the topography data.
Use the Autolink tool twice. After that you should repeat the standard procedure:
- Select all basins
- Clean Hydro Connections
- Set HAROID
