Deflt3D模型在鄱阳湖码头工程防洪评价中的应用OA
Application of Deflt3D model to flood control impact evaluation at Poyang Lake Dock
采用Delft3D二维数学模型模拟鄱阳湖入江水道水流,结合港区3座码头涉河建设方案,合理进行矩形网格划分,利用实测的上游五河来水及下游湖口站水位资料进行率定和验证,确定模拟河段糙率系数和涡黏系数.选用2种边界条件,计算码头建设前后水位和流速变化数值,经过数据处理,形成工程建设前后水位和流速差值等值线图,得出港区3座码头最大壅水高度为0.95 cm,流速增加最大值为0.17 m/s,即工程建设对鄱阳湖入江水道壅水和流速影响均不大.这表明Delft3…查看全部>>
Using the Delft3D two-dimensional mathematical model to simulate the water flow in the Poyang Lake inflow channel,combined with the construction plans of three docks in the port area,a reasonable rectangular grid division was car-ried out.The measured water level data from the upstream five rivers and the downstream Hukou station were used for cali-bration and verification to determine the roughness coefficient and eddy viscosity coefficient of the simulated…查看全部>>
