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 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 soil profile: xxx.

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: H_vw = 13 m
Marge = 2 H_vw + 1.5 (H - H_vw) = xxx m
Assessment level: Z = xxx m
X_Ssign = xxx m
X_Szv = xxx m
