Wave flume experiments on the formation of longshore bars produced by breaking waves

Description :
Mechanisms and processes of longshore bar formation were investigated in connection with vortices induced by breaking waves in the laboratory. Four kinds of wave-flume experiments were conducted using a two-video-camera system to examine the vortices and bar formation in detail. Four process models on bar formation are constructed based on the action of vortices: they are models for break-point single bar, inshore single bar, successive multiple bars, and simultaneous multiple bars. The occurrence condition for these four types of bars can be quantitatively determined.
