The Effect of Beach Slope on Oscillatory Flow Bedload Transport

by David B. King, Jr., Univ of California, San Diego, United States,

Document Type: Proceeding Paper

Part of: Coastal Sediments


The data for five laboratory sloping bed bedload sediment transport experiments are presented. Each consists of a series of half cycle transport rate measurements using the same waveform and sediment size but different bed slopes. The data agree well with Bagnold (1963)'s theoretical development for a value of φ near 30°. Using his formulation, a model is developed to modify any flat bed transport model to account for the effects of bed slope.
