H-ADCP計測と数値解析を組み合わせた浮遊土砂輸送量計測システムの提案

抄録

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.
