Split a subcatchment
To be able to easily split a subcatchment into 2 separate subcatchments.
For example when it becomes obvious that the flow from a subcatchment cannot be collected at a pit (node), it becomes necessary to insert an additional pit (node) to capture flows. The subcatchment needs to be easily split (say with a general line) into 2 separate subcatchments with similar data other than the new areas.

Thanks for that Sophia. Yes that certainly does work; however it is a bit of a pain having to create the selection sets. Pity it wasn't just a bit more intuitive,

This could be achieved by drawing a polygon around the portion of subcatchment you want to split and then use the tool model > geometry > crop selected overlapping polygons.
