Description
This benchmark tests all possible trajectories according to the Global check. Those trajectories are:
- Case A: step 1 = No → Global check passed
- Case B: step 1 = Yes, step 2 = No, step 4 = No → Global check passed
- Case C: step 1 = Yes, step 2 = No, step 4 = Yes, step 5 = No → Global check passed
- Case D: step 1 = Yes, step 2 = No, step 4 = Yes, step 5 = Yes → Global check failed
- Case E: step 1 = Yes, step 2 = Yes → Global check failed
For case A, the same input as benchmark 1-1 (see group 1) is used except for the surface line: the length of the foreland is increased to 160 m (instead of 60 m).
For case B, the same input as benchmark 1-1 (see group 1) is used except for xxx: xxx.
For case C, the same input as benchmark 1-1 (see group 1) is used except for xxx: xxx.
For case D, the same input as benchmark 1-1 (see group 1) is used.
For case E, the same input as benchmark 1-1 (see group 1) is used except for xxx: xxx.
Benchmarks results
Hereafter are given the analytical results per case.
...
Case A:
...
Channel depth: H = 15 m
Thickness of the sensitive layer: Hvw = 10 m
Marge = 2 Hvw + 1.5 (H - Hvw) = 27.5 m
Slope of the observation profile: 1:15
Assessment level: Z = -10 m
XSsign = 72.5 m
XSzv = 30 m
D-Flow Slide results
D-FLOW SLIDE results are in accordance with the results by hand as show in the tables below.
