DISSIPATION OF WAVE ENERGY DUE TO OPPOSING CURRENT

Toshio Iwasaki, Michio Sato

Abstract


Energy dissipation and wave height attenuation were analysed theoretically for surface waves propagating against uniform flow. Energy dissipation was estimated from evaluation of work "by internal and boundary shear stresses. Experiments were conducted in a test flume of 20m long, 0.8m wide and 0.5m high. Results showed that tested values of rate of wave height attenuation were comparable with theoretical values.

Keywords
