Group 3: Benchmarks from spreadsheets
This section uses tests performed by hand or by means of an Excel spreadsheet.
3.1 Test of all possible trajectories of the Global check
Description
This benchmark tests all possible trajectories according to the Global check. Those trajectories are:
| Case | Step 1 | Step 3 | Step 4 | Step 5 | Step 6 | Step 7 | Global check |
|---|---|---|---|---|---|---|---|
| A | No | Pass | |||||
| B | Yes | Yes | Fail | ||||
| C | Yes | No | No | Pass | |||
| D | Yes | No | Yes | Yes | Fail | ||
| E | Yes | No | Yes | No | Yes | Fail | |
| F | Yes | No | Yes | No | No | Yes | Fail |
| G | Yes | No | Yes | No | No | No | Pass |
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
