The wave-induced erosion processes involved in the interaction of revetments and dunes are investigated by means of small scale experiments performed in the 3D wave basin of Leichtweiss-lnstitute for Hydraulic Engineering and Water Resources (LWI) in Braunschweig, Germany. Two adjacent revetments (R1 and R2) were constructed with an angle of δ=22° in plane. Irregular JONSWAP waves were generated at two water depths, which resulted in two different wave overtopping rates. The influences of the wave attack angle and wave overtopping rate on dune erosion behind the revetments are investigated by means of laboratory tests and the results are discussed.
