- in case no revetment is present: M = 2 Hgeul with Hgeul is the channel depth
- in case a revetment is present: M = Max [ Mbestorting ; 2 Honbest) ]
...
Hgeul is the channel depth in case no revetment is present and Hgeul = Honbest in case a revetment is present
Honbest is the depth of the channel below the revetment.
Mbestorting is the horizontal projection of the length of the revetment

NOTE: In case the user-defined sand type is "very fine sand", the breach flow criteria cannot be checked and the program gives always that . The program indicates breach flow is possible and a warning message will be given in the Overall Results window.
