SEDIMENT TRANSPORTATION OF MUD-DUMPING GROUND AND EFFECT ON SEAWAY SILTATION OF HUANGHUA PORT

Particle tracking, neutron activation tracer sediment technique and formulas of Zhao and Yalin have been used to conduct research on sediment transport in mud-dumping grounds of Huanghua port. Furthermore, through these studies, effect on seaway siltation is analyzed. Results show that the sediment transport is dominated by tidal current under normal weather; nevertheless, under the condition of strong winds,wind wave, tidal current and wind-driven current play important roles in the sediment transport. Sediments from the mud-dumping grounds almost have no direct effect on seaway siltation under a single strong wind. The effect on seaway siltation from the mud-dumping grounds is indirect and limited.
