东江博罗浅段航道整治工程数值模拟

Numerical Simulation of the Channel Regulation in Boluo Shallow Reach of Dongjiang River

采用一维三级联解方法,对东江惠州-东江口范围进行建模、率定和验证,计算和分析在各种设计水文组次(设计最小通航流量、整治流量、各级洪水流量)下,6个整治工程方案对博罗浅段水位和流速的影响,并确定推荐方案。验证结果表明:模型较好地模拟了河道的实际情况,可用于各工程方案之对比。

A 1-dimensional hydrodynamic model is developed for model establishment, rating, and verification of the scope from Huizhong of Dongjinag River to Dongjiang River Estuary, calculating and analyzing the influence of 6 regulation schemes to the water stage and flow speed of Boluo shallow reach under design minimum anvigation discharge, regulation discharge and all flood discharge, and determining the recommended scheme. The verification result shows that the model well simulates the real situation of the channel, and can be used for comparison of all engineering schemes.
