XSsign > XSzv => Flow slide would not lead to damage on levee => Global check passes.
Detailed check: ( see table below for intermediary results) Probability of flood damage by liquefaction (= 0.00) < Allowable probability of failure (2.50 × 10-6) => Detailed check passes.D-Flow Slide results
Overall check: as Global and Detailed check pass, the The Overall check gives a Warning message because D50 < 200 μm , an Advanced check is therefore needed.
...
Global check - Step 1c: The foreland is artificial => Global and Detailed check fail, an Advanced check is needed.
Detailed check: ( see table below for intermediary results) Probability of flood damage by liquefaction < Allowable probability of failure => Detailed check passes.D-Flow Slide results
Overall check: as step 1c of Global check fails, the Overall check fails whatever the Detailed check result. The Overall check gives a Information message as the Global check fails.
Case C:
Global check - Step 1a:
...
Global check - Step 1d: The average slope over a height of at least 5 m is 1:3.901 so steeper than 1:4 => Flow slide is possible based on criterium "steepest slope over 5 m" => Global check fails.
Detailed check: ( see table below for intermediary results) Probability of flood damage by liquefaction > Allowable probability of failure => Detailed check fails.D-Flow Slide results
Overall check: the Overall result gives a warning Warning because the criteria on "steepest slope over 5 m" is met, an Advanced check is therefore needed.
