SUSPENDED SEDIMENT CONCENTRATION PROFILES UNDER NON-BREAKING AND BREAKING WAVES

Rattanapitikon Winyu, Tomoya Shibayama

Abstract


Simple formulas to predict time-averaged suspended sediment concentration are formulated using steady diffusion equation. Empirical formulas are developed to compute reference concentration (boundary condition) and diffusion coefficient. For suspended sediment concentration in the field, the same formulas with regular wave condition can be applied by using root mean square wave height and average wave period. Total 139 data sets are used for calibration of empirical formulas and 175 data sets are used for verification.
