Abstract
The ADP is an advanced piece of oceanographic equipment that measures water speed and direction profiles from the acoustic Doppler principle. In recent years, the strength of the acoustic backscatter obtained from ADP has been used to measure vertically suspended sediment concentration(SSC) profiles. In this study, an ADP was installed in coastal waters near Yumsan, on the west coast of Korea, and flow and sediment data were gathered simultaneously. SSC concentrations were calculated from the acoustic backscatter strengths adjusted by using calibrated acoustic coefficients. The observed SSC profiles were compared with analytical solutions and showed good agreement. Simultaneously, the suspended material fluxes were analyzed in detail. ADP was very useful for measuring the vertically distributed suspended sediment concentrations and flow velocity profiles.
