大虎水道东南部水域海砂开采水动力环境影响及泥沙扩散浓度预测

Effects of Sand Exploitation in Water Area South the Dohu Channel on HydrodynamicEnvironment and Prediction of Sediment Diffusion Density

采用水流泥沙数学模型对大虎水道东南部海砂开采后的水动力条件变化、开采过程中的泥沙扩散及开采后的河床冲淤状况变化进行了预测分析,对海砂开采的管理提出了若干建议。

A mathematic Model of flow and sediment was employed to predict and analize the change of hydrodynamic condition,the sediment diffusion during the process of exploitation and the change of scour and silting situation in the channel bed after sand exploitation in the southeast part of Dahu Channel.The paper put forword some suggestions about the management of sea sand exploitation.
