FIELD TESTS OF RADIATION-STRESS ESTIMATORS OF LONGSHORE SEDIMENT-TRANSPORT

Thomas E. White

Abstract


Surfzone measurements of longshore sediment-transport with optical backscatter sensors and current meters are compared to transport estimates from offshore wave data. Several methods from the Shore Protection Manual for computing longshore sediment transport from waves are compared and correlated. Some formulas work well some of the time. Circumstances of which equations perform well/poorly under which conditions are specified, and reasons for poor performances are speculated upon. Advice is given for placement of wave gages and methods of analysis, which would increase the probability of obtaining good estimates of longshore sediment transport from directional wave data.
