中文摘要：
利用平面二维水动力及泥沙输运模型、有限元法对银洲湖及邻近水域内的悬沙输运、流速分布、水流平面形态等进行了数值模拟计算.其中黏性泥沙输运模型考虑侵蚀和沉积剪切应力.计算结果与实测结果比较表明：银洲湖水域的潮流大体上呈现沿航道南北向的往复流,径流和潮流是银洲湖水域的主要动力因素,细颗粒悬浮泥沙输运是该水域泥沙的主要运动形式;平面二维水动力及泥沙输运模型能较好地复演银洲湖水域的潮流泥沙场,可用于实际工程潮流泥沙场的计算.
英文摘要：
By use of the 2D plane hydrodynamic and sediment transport finite element model, the suspended sediment field, tidal current field, and plane flow pattern were simulated and calculated. The erosion and deposition-induced shear stresses were considered in cohesive sediment transport model. The comparison of the calculated result with the measured data shows that the reciprocal flow in south and north directions along the navigation channel is the main form of tides in Yinzhouhu waters, runoff and tidal flow are the main dynamic factors of Yinzhouhu waters, and fine-particle suspended sediment transport is the main form of sediment movement. As a result, the 2D plane hydrodynamic and sediment transport model is effective for simulating the tidal and sediment fields, and can be used in practical projects.
