EXCITATION OF EDGE WAVES ON AN EXPONENTIAL BEACH

Summary:
Edge waves are the longshore, trapped waves; their amplitude diminishes exponentially seaward from the shoreline. Ursell [1] has shown that there is a family of edge wave solutions of the shallow water equations, and Ball [2] provided a normal mode solution for the exponential beach. This study investigated, experimentally, the excitation of edge waves on a concave exponential beach by waves normally incident on the beach. The experimental investigation included the study of edge wave frequency, amplitude and particle motions. The results indicated that resonance occurs under suitable conditions for edge wave excitation. Viscosity, nonlinearity and defraction at the beach sidewalls reduced agreement between experiments and theory. The effects of these parameters on edge waves should be explored in more detail in further research.
