For case C, the same input as benchmark 1-1 (see group 1) is used except for xxx: xxxthe position of the characteristic point "Insert river channel" which is lowered to get a slope channel of 1 : 7,1.
For case D, the same input as benchmark 1-1 (see group 1) is used.

Results of benchmark 3-1 for case B
The overall result is not correctly determined in D-Flow Slide if the foreshore is artificial: D-Flow Slide uses the Detailed check result but it should directly conclude that the Overall check fails.
