Overall check: as Global and Detailed check pass, the Overall passes. 

 

Case H:

Global check - Step 1a: Flow slide would lead to damage on levee => Go to step 1c.

Global check - Step 1c: The foreland is natural => Go to step 1d.

Global check - Step 1d: The average slope over a height of at least 5 m is 1:7.1 so softer than 1:4 => Flow slide is not possible based on criterium "steepest slope over 5 m" => Go to step 1e.

Global check - Step 1e:

The slope channel is 1:7.1, so the slope is softer than the critical (local) slope from the CUR table (not too fine sand with  D50 = 230 μm and D15 = 130 μm) => Breaching is not possible.

And the total slope is 1:7.1 so softer than 1:7

=> Flow slide is not possible based on average slope => Global check passes.

Detailed check: (see table below for intermediary results) Probability of flood damage by liquefaction  > Allowable probability of failure  => Detailed check fails.

Overall check: Global passes and Detailed checks fails, that's not logical, so a warning message is displayed in the Overall check.
