Step 6: Are there layers present with a thickness of minimal 5 m, in which D50 < 200 μm or D15 < 100 μm averaged over a thickness of 5 m?
The answer is "Yes" if D50 if D50 < 200 μm or D15 < D15 < 100 μm where D15 and D50 are the minimum averaged values (only for sand and gravel soils) averaged over over a thickness of 5 m between the water line and the toe of the channel slope.

If so then the slope is breaching sensitive, so the check FAILED, so a Detailed check is needed. In the case the slope height is over 40 m a Detailed check is also needed.
if If not then the check SUCCEEDED.
