In case of natural deposited slopes, go to step 1d.
Step 1d:
...
Is flow slide possible based on the occurrence criterion of "the steepest slope over 5 m"?
If the previous step (step 1c) has not been passed, a check on the first of two occurrence criteria (“optredingscriteria”) must be performed.
The occurrence of A flow slide is possible can occur if the following condition is met: the average slope is steeper than or equal to 1:4, over a height of at least 5 m.
...
If this occurrence criterion not met, go to step 1e.
Step 1e:
...
Is flow slide possible based on the occurrence criterion based on average geometry ?
If the previous step (step 1d) has not been passed, a check on the second occurrence criterion a check on the average geometry must be must be performed.
The occurrence of flow slide is possible if A flow slide can occur if one of the two following conditions is met:
