Fig. 6.6 Discharge factors with wave return walls for (a) imperméable slopes
and (b) permeable slopes [Besley, 1999].
Where d'is the depth of water at the toe of structure for which reflecting
waves dominate when h* > 0.3 and impacting waves when h* < 0.3. For the
former, the mean overtopping discharge per métré run of wall is given as:
