Model Behaviour under Medium Waves

This is the second of three model tests carried out to compare the effects of wave height.

In this case the waves are of intermediate height.

As can be seen the drainage arrays are in place, thereby indicating that berms are receiving the benefit of inwardly directed Seepage Forces.

In this test there is some limited erosion experienced along the crest and on the upstream slope of the sandfill. Otherwise, there is obviously no significant endangerment of the berm.
