Wave Overtopping Flow Analysis
The combined action of environmental forcing (waves, currents, et.c.), decreasing fluvial sediment supply, and intense anthropogenic activity, results in severe erosion problems in coastal areas. A frequently used coastal protection measure is the construction of detached breakwaters parallel to the coastline, for the proper design of which, one critical aspect is the behavior of the induced flow in their vicinity. In the present work the wave induced flow in the vicinity of a low-crested breakwater with zero freeboard is studied experimentally. The geometrical scale of the physical model was 1/30, and it was placed on a sloping beach of 1/15.
