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?
...
- The total slope (channel edge-channel bottom) is on average steeper than or equal to 1 : [7 × (HR/24)(1/3) ], in which HR is defined in the figure below.
- Breaching is possible (see paragraph below called "Breaching criteria")
...
If the criteria of occurrence is not met, the Global and the Overall checks SUCCEED.
Breach flow criteria:
