| Abstract: | The flow characteristics of breaking solitary waves on plane beaches are investigated with emphasis on the run-up and draw-down processes. A series of experiments were conducted in the SUPER TANK of Tainan Hydraulics Laboratory with three plane beaches of 1:20, 1:40 and 1:60. Solitary waves of which relative wave heights ranged from 0.031 to 0.231 were generated. The surface elevation changes were recorded by capacitance type wave gages distributed at 96 stations. The velocities were measured by acoustic Doppler velocimeters and electric-magnetic velocimeters. The surface wave profiles evolutions and velocity time series are displayed and discussed. In addition, the run-up heights and the breaking index obtained from this large-scale experiment are also shown and are compared to results of previous studies. | |
