摘要
为评估吉林省饮马河洪水风险,构建MIKE 11和MIKE 21一、二维耦合洪水演进数值模拟模型,利用2010年德惠水文站汛期实测洪水过程和已有水面线成果对模型重要参数进行验证,使模型具有较高模拟精度。以陈家崴子溃口20年一遇洪水方案为例进行洪水分析,经淹没区和耦合模型两方面水量平衡分析,说明模型模拟结果合理且可靠。
In order to estimate the flood risk of Yinma river,1D and 2D coupling flood routing numerical simulation model of MIKE 11 and MIKE 21 was established.The important parameters of the model were verified by using the measured flood process of 2010 Dehui hydrological station and the existing water surface profile results,the results showed that the model had high simulation accuracy.Taking the 20-year flood plan of Chenjiawaizi breach as an example,flood analysis was carried out,after the water balance analysis of the submerged area and the coupling model,it showed that the simulation results of the model were reasonable and reliable.
