The bank failure algorithm computes a critical failure plane at every one percent of the elevation between the toe and edge stations, computing critical failure planes at 100 evenly spaced vertical bank intersection points (see Steps in a Bank Failure Analysis, first figure). This is computationally expensive and often much more detail than necessary and the parameter is editable in HEC-RAS. Users can specify the number of vertical computation bank failure points. HEC-RAS will evenly distribute the computation points vertically, between the bank toe and edge elevations.
