Abstract

Abstract

A suspended sediment concentration(SSC) is retrieved from the Landsat images during 1986-2004 in the Laizhou Bay of Shandong Province, China using the model that is established according to the field measurement data off the Huanghe River mouth. The transportation, distribution and deposition of the suspended sediment are estimated in the Laizhou Bay. The relationships between the distribution of suspended sediment and the change of submarine topography and ocean dynamic are also discussed, the combination of hydrological and meteorological data, depth measurement data and the numerical simulation results of extreme weather in the southwest area of the Laizhou Bay. The results show that the zone of turbidity maximum is inferred in the Huanghe River mouth and near the southwest shore of the Laizhou Bay, and the turbid water during low discharge period covers a much larger area than in the flood season. Ahigher current velocity field off the Huanghe River mouth is companied usually with the higher magnitude of the SSC. The suspended sediment mainly originates from river discharge and resuspension near the Huanghe River mouth. However, the zone of turbidity maximum near the southwest shore primarily caused by the resuspension of the bottom surface sediments induced by tidal currents. The water/sediment discharge from the Huanghe River controlls the magnitude of the SSC, and the distribution of SSC caused by wind and spring-neap tidal cycle is usually smaller than the SSC variations caused by tidal current fields. In the extreme weather condition, the SSC increases significantly in the shallow coastal areas of the southwest Laizhou Bay.
