A MONITORING SYSTEM FOR SUSPENDED-SEDIMENT TRANSPORT USING H-ADCP MEASUREMENT AND NUMERICAL SIMULATION

Abstract

To realize an accurate and continuous monitoring for suspended-sediment transport, we attempt to develop a new real-time monitoring system with H-ADCP (horizontal acoustic Doppler current profiler) measurement and numerical simulation, in which the dynamic interpolation and extrapolation (DIEX) method recently developed by the authors is extended to conduct sediment-transport simulation. To validate the fundamental performance of the present system, we have applied the present system to evaluate the river discharge and suspended-sediment transport at the Edo River. The simulated suspended-sediment transport was compared with the observed data, showing the high performance of the present monitoring system for suspended-sediment transport.
