Abstract

Siltation mechanism in a 14km long approach channel on large scale muddy tidal flat is studied based on field investigations and numerical simulation. Natural conditions such as river discharge, waves, tides, tidal currents, and bed materials were measured over one year. The morphological change shows some relations with the grain size distribution of bed materials and current flow patterns. The net movement pattern of bed materials in the muddy tidal flat is given by the analysis of the field data. From the numerical simulation, it is revealed that the resuspended bed materials by waves from the surrounding tidal flat play an important role in the siltation process of the approach channel.
