马颊河为山东省海河流域的主要排水河道,由于海洋泥沙运动的特性,其入海口处泥沙回流淤积。运用数学模拟手段,建立了马颊河河口二维非恒定流水沙数学模型,并根据实测地形、水文资料进行了水流、泥沙模型验证,根据马颊河河口特点和清淤长度、宽度、深度与回淤率之间的关系,拟定了不同的河道整治方案,并对不同方案的泄量、回淤量进行了模拟分析,选出了最优方案。 Majia River is the main drainage channel of the Haihe River Basin in Shandong Province. Because of the characteristics of marine sediment movement, the sediment at the mouth of the sea flows back and silts. Based on the measured terrain and hydrological data, a mathematical model was established to simulate the unsteady flow and runoff of Majiahe River Estuary. According to the characteristics of the estuary and the length, width and depth of dredging, And the relationship between the rate of return silt, developed a different river regulation program, and different programs of the amount of discharge, back silting the amount of simulation analysis, select the optimal solution.
