The factor based on berm location relative to the swl is given by

where
dh = elevation difference between most seaward berm point and swl
The factor rdh is confined to the range 1≥ rdh ≥0.
The impact of a berm on the value calculated for γb by the preceding pro-
cedure depends in physically meaningful ways on the particular berm configura-
tion. The factor rdh has maximum impact when the swl coincides with the
