h1. Group 3: Benchmarks from spreadsheets

This section uses tests performed by hand or by means of an Excel spreadsheet.

h2. 3.1 Test of all possible trajectories of the Global check

h5. 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|GEO:D-Flow Slide - Group 1]) is used except for the soilsurface profile: xxxline: 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|GEO:D-Flow Slide - Group 1]) is used except for xxx: xxx.

For case C, the same input as benchmark 1-1 (see [group 1|GEO:D-Flow Slide - Group 1]) is used except for xxx: xxx.

For case D, the same input as benchmark 1-1 (see [group 1|GEO:D-Flow Slide - Group 1]) is used.

For case E, the same input as benchmark 1-1 (see [group 1|GEO:D-Flow Slide - Group 1]) is used except for xxx: xxx.

h5. Benchmarks results

Hereafter are given the analytical results per case.

h6. Case A:

Channel depth: H = 15 m
Thickness of the sensitive layer: H{~}vw~ = 1310 m
Marge = 2 H{~}vw~ + 1.5 (H - H{~}vw~) = xxx27.5 m

Slope of the observation profile: 1:15
Assessment level: Z = xxx\-10 m
X{~}Ssign~ = xxx72.5 m
X{~}Szv~ = xxx30 m
