崎岖列岛邻近海域具有良好的水深条件 ,为了开发和利用这一资源 ,于 1 996年冬季和1 997年夏季 ,对该海域进行了水文泥沙调查。分析结果表明 ,该海域的水动力条件取决于长江和钱塘江径流与潮流、波浪的力量对比 ;其泥沙的输运和沉积主要受制于长江口南下泥沙量的多少及水动力的强弱。从动力学的角度阐述了该区泥沙输运和沉积机制 ,得出流急、悬沙浓度高而落淤少是该地区的特点。
In order to develop and utilize this resource, the waters adjacent to the rugged islands have good water depth conditions. Hydrological sediment surveys were conducted in the winter of 1996 and the summer of 1997. The results show that the hydrodynamic conditions of the sea area depend on the runoff and tidal currents of the Yangtze River and the Qiantang River, and the strength of the waves. The sediment transport and sedimentation are mainly controlled by the amount of sediment in the south of the Yangtze River estuary and the hydrodynamic strength . The mechanism of sediment transport and sedimentation in this area is expatiated from the point of view of dynamics. It is concluded that there are some problems, such as rapid flow, high suspended sediment concentration and less sedimentation.
