中文摘要:

在 Hangzhou 海湾的沉积运输由于它的深测术和水动力学条件是极其复杂的。ECOMSED 模特儿被雇用模仿三维(3-D ) 在 Hangzhou 的连贯的沉积运输海湾。象 Coriolis 力量,潮,咸度,河分泌物,和波浪那样的动态因素在模型被考虑。包括重要波浪高度,时期,和方向,波浪参数与 SWAN 模型一起被计算。Grant-Madsen 模型为床被介绍砍由于波浪和水流的联合效果强调。床的明确的表达砍过去常计算下沉 / 采购学期的应力基于足够地与测量数据验证了明确的表达的以前的研究被修改。综合模型上述模型被使用在 Hangzhou 模仿沉积运输海湾。模拟的结果有关推迟的沉积的分发与领域观察同意很好,显示沉积显著地在在波浪和水流的行动下面的 Hangzhou 海湾被推迟。

英文摘要:

Sediment transport in the Hangzhou Bay is extremely complicated due to its bathymetry and hydrodynamic conditions. The ECOMSED model is employed to simulate three-dimensional (3-D) cohesive sediment transport in Hangzhou Bay. Dynamical factors such as Coriolis force, tides, salinity, river discharges, and waves are considered in the model. The wave parameters, including the significant wave height, period, and direction, are calculated with the SWAN model. The Grant-Madsen model is introduced for the bed shear stress due to the combined effect of waves and currents. The formulation of bed shear stress used to calculate the sink/source terms is modified based on previous research that sufficiently validated the formulation with measurement data. The integrated model of the above-mentioned models is applied to simulate sediment transport in Hangzhou Bay. The results of the simulation agree well with field observations concerning the distribution of suspended sediment, indicating that the sediments are remarkably suspended in Hangzhou Bay under the action of waves and currents.
