Abstract

In the present paper, the mobile measurement of tidal current was conducted by using the developed system with ADCP and D-GPS over the wide area in Bisanseto fairway. On the basis of the measurement, the sediment transport mechanism and the dynamics of sand wave formation is understood, and then, the fundamental information is obtained for the maintenance of the fairway. In the flood and ebb tides, the amplitude of tidal current in the upper layer is similar to it in the lower layer, but the current direction is slightly different near the deeper part.
