In-situ Lagrangian-Acoustic Drogue (LAD) has been developed for estimating the sediment transport parameters in intertidal regions with very shallow water. The new drogue is equipped with a Global Positioning System (GPS), Acoustic Doppler Current Profiler (ADCP) and nephelometers. The accuracy of a current profile measured using this in strument is verified in two different conditions; uni-directional flow and multi-directional flow. The field observation results support the conventional concept of suspended sediment as a vertical balance between downward suspended sediment settling and upward turbulent diffusion fluxes. The results may indicate that the new drogue is adequate for estimating the sediment settling velocity in the field.
