Global check - Step 1d: The average slope over a height of at least 5 m is 1:2 5 so steeper than 1:4 => Flow slide is possible not possible based on criterium "steepest slope over 5 m" => Go to step 1e.

Global check - Step 1e:

The slope channel is 1:65, 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.
