摘要：

This paper examines the swash oscillation induced by bichromatic waves on sloping beaches. In particular, a series of physical experiments for three different sloping beaches of 1/10, 1/20 and 1/40 were conducted in a long wave flume (300 m x 5 m x 5.2 m) at Tainan Hydraulics Laboratory to investigate the swash motion. Ninety-three wave gauges along the wave flume and three run-up wires parallel to the sloping bottom were used. Detailed analyses of the swash motion dependence on beach slope, incident wave energy, and frequency difference are given. The cross-shore structures of long wave components are also examined.
