Input screen: The probabilistic parameters are fixed,
Only the Mean "Area ratio" can be changed (white box)
Note: In version 16.1 the Allowable probability of failure is no longer an input parameter. Consequently, no decision can be made whether or not the method meets its failure criteria,

Cohesive layers factor | Cohesieve lagen factor | Factor which evaluates the presence of cohesive layers or peat layers within the sand body. Cohesive and peat layers start to play a role if their (individual) thickness is larger than 0,5 m (CUR113, 2008). If their thickness exceeds 5 m it can be assumed in most situations the breach will be stopped. The following values are proposed:
