In case of slopes

The calculation rule gives the reflection coefficient for various structures: smooth impermeable slopes, slopes with rubble or concrete elements and vertical structures. Reflection occurs if the bottom or angle of slope is steeper than ca. 1:15, and the angle of wave approach is greater than ca. 10 degrees. (This is the angle between the wave crest and the normal to the bank or the angle between the wave direction and the line of the dike).

Smooth impermeable slope:

    (equation 1)

Rubble slopes:

    (equation 2)

Slopes with concrete elements:
