Comparison and analysis of different longshore sediment transport formulas
摘要
Abstract
The longshore sediment transport has been intensively investigated in the past nearly one hundred years and numerous formulas have been proposed to predict the longshore sediment transport rate.However,the accuracy and applicability of those formulas remain unknown.In this study,seven formulas that have been widely used are compared to find a formula with high accuracy and wide applicability.The observations of the prototype coast and the indoor wave pool testing data using both natural sand and light sand are collected,screened,and filtered.The seven formulas are applied to all the collected data,and the root mean square deviations(Srms)are computed.The results show that the CERC formula and Kamphuis formula are more suitable for on-site use.The Srms between the two formulas and the indoor testing data of the light sand is relatively high.The MH-Kamphuis formula and van Rijn formula generally underestimate the measured data.The Zhao Jinsheng formula and Bayram formula have relatively high Srms.The Sun Linyun formula turns out to have relatively high prediction accuracy.The Srms for the Sun Linyun formula is 36％-73％lower than other formulas.The Sun Linyun formula shows a higher overall agreement with the measurements of both natural and light sand,demonstrating its potential use in model similarity laws.关键词
