摘要
行洪排涝是平原河网区汛期的重要任务。利用MIKE11模型中的HD模块,以江苏省泗洪县城区水系为实例,建立了一维水动力学模型,并利用产汇流计算确定了模型的边界条件,对20年一遇暴雨条件下的城区河网水量进行了模拟计算。结果表明,在现有的排涝设施条件下,泗洪县城区河网能够满足设计暴雨下的排涝要求。
Flood defence and drainage are the mental task in the river networks in plains. This paper establishes a 1-D hydrodynamic model by using HD in MIKE11 model to get the boundary conditions of the model by means of produced convergence. And then a simulation is conducted of the river network of the city under the conditions of a rainstorm within 20 years. The results show that the river networks of Sihong County can meet the requirements of the designed rainstorm under the existing conditions.
