Development of acoustic suspended sediment monitor

An acoustic suspended sediment monitor (ASSM) has been developed for the observation of suspatded sediment ooncanration profiler in water,rmnitoring pollutants in water and for the studies of ooestal sediment trensportatmn and deposition.The determination of the main technical parameters and the methodokogy of resdving the key technique and laboratory calibration are reviewed.The ASSM was applied to observe the suspended sediment in the Changjiang Estuary,whose typical suspended sediment concentration Profilers have been obtained.
