在分析圩垸型河网地区行洪除涝特点基础上,提出了该地区行洪除涝水面率的确定方法———即从不同水域承载的行洪和除涝功能分别计算其水面率,再将二者结合起来确定其行洪除涝水面率。实例验证表明,该方法合理可行。
On the basis of analyzing the characteristics of flood discharge and waterlogging in the embankment riverbed area, this paper puts forward the method to determine the surface waterlogging removal flood rate in this area --- that is, calculating the water surface rate separately from the flood carrying and waterlogging carrying functions in different watersheds, Then combine the two to determine the flood rate of waterlogging surface area. The example verification shows that this method is reasonable and feasible.
