LITTORAL TRANSPORT RATE

[摘要] This paper describes a study of littoral sediment transport rate based on three-dimensional hydraulic model experiments performed with regular and irregular waves. Deep water wave conditions, wave heights through the surf zone, wave breaking angles, longshore current velocity distribution and the bed load and suspended load sediment transport distributions were measured simultaneously to form a coherent data set. An expression is developed linking sediment transport rate to wave steepness, beach slope, relative grain size and breaking angle. The expression compares well with published field data.
