Global check - Step 3: The foreland is artificial => Global and Detailed check fail, an Advanced check is needed.
Detailed check: see table below: Probability of flood damage by liquefaction < Allowable probability of failure => Detailed check passes.
Overall check: as step 3 of Global check fails, the Overall check fails whatever the Detailed check result.
Case C:
Global check - Step 1: Same results as benchmark 1-1 (flow slide would lead to damage on levee) => Go to step 3.
