深圳河河口围垦对防洪和河床冲淤影响研究

为研究深圳河河口福田保税区围垦填土占用部分河道对深圳河治理工程的影响 ,建立了贴体坐标系下平面二维的深圳河河道 -河口 -海湾整体水域的水流泥沙数学模型 ,计算了不同频率洪峰流量和河口潮位过程组合下河口围垦所造成的深圳河沿程水位抬高程度和河床冲淤变化情况 ,提出了建议的挖除方案

Study on effects of estuarin e reclamation on flood control and erosion of riverbed in Shenzhen River

In order to study the influence of the partial occupation of river channel due to the reclamation in the Shenzhen river estuary on the Shenzhen river regulation project, a two dimensional numerical model of the flow motion and the sediment transport in the body-fitted coordinate is established and applied to the integral river-estuary-bay water area of Shenzhen region. The water level and the erosion and/or deposition of riverbed along the Shenzhen river is computed for different hydrometric and topographic conditions. Furthermore, the scheme of reclamation is proposed.
