* Comment: Overtopping calculated with a smooth slope (roughness factor = 1,0).
This number needs to be entered in case of overtopping.

Result


Application area
For this calculation the following criterion applies: ϒbξm-1,0 ≤ 1,8
ϒb = influence factor for the presence of a berm
ξm-1,0 = breaker parameter based on the spectral wave period Tm-1,0 If this criterion cannot be fulfilled, than the influence factor for roughness can be corrected with the procedure as described in TAW (2002a). This criterion does not only apply to Hillblocks, but to all types of revetment blocks.
