Detailed check: see table below for intermediary results: Probability of flood damage by liquefaction < Allowable probability of failure => Detailed check passes.
Overall check: as Detailed check passes, the Overall check passes.
Case F:
Global check - Step 1: Same results as benchmark 1-1 (flow slide would lead to damage on levee) => Go to step 3.
Global check - Step 3: The foreland is natural => Go to step 4.
Global check - Step 4: The slope channel is 1:6 so softer than 1:7 => Flow slide is possible based on geometry => Go to step 5.
Global check - Step 5: The state parameter is -0.06 so less than -0.05 => Liquefaction is not possible based on the state parameter => Go to step 6.
Global check - Step 6: The average diameters over a thickness of 5m are D50 = 250 μm and D15 = 150 μm. So no layers are present with D50 < 200 μm and D15 < 100 μm => Go to step 7.
Global check - Step 7: The slope channel is 1:2, so the slope is steeper than the critical (local) slope from the CUR table => Global check fails and Detailed check needed.
Detailed check: see table below for intermediary results: Probability of flood damage by liquefaction > Allowable probability of failure => Detailed check fails.
Overall check: Global and Detailed checks fail, so the , the Overall check fails whatever the Detailed check result.
