Abstract:

摘要: 以三维斜压动力—悬沙模型ECOMSED联合第三代海浪模型SWAN及Grant-Madsen浪流耦合底边界层模型,对黄河入海泥沙悬移扩散的时空变化过程进行了数值模拟。通过5项控制试验,初步揭示了不同动力因子对黄河入海泥沙悬移输送的贡献和影响。研究结果表明,单纯潮流作用下黄河入海悬沙不能形成长距离输送。风海流作用下,绝大部分悬沙直接沉降在黄河三角洲的附近,只有非常小的部分发生长距离输送。风场作用下,黄河入海悬沙主要向北-西北方向输送,部分输往莱州湾的悬沙继续向北输送。环流作用下,悬沙输送具有明显的三维结构,分层结构与环流结构基本一致,而深度平均的悬沙输送通量与环流结构有较大的差别。浪流联合作用下的悬沙浓度变化与底剪切应力都呈现为10天左右的变化周期,表明其变化主要是由风应力所控制。
