一、关于设计洪水与设计洪水过程线的涵义所谓设计洪水,简单说来就是按某一设计标准所拟定的洪水。设计标准则是根据客观上的需要拟定的。随着工程规模、任务、性质等的不同,设计标准也不相同。但由于水文资料的积累是长期的、相对短暂的,其所反映的水文规律,在特殊情况下我们认识得不够。因而,为了进行经济比较和校核水工建筑物 First, on the design of flood and design flood process line implications The so-called design flood, in short, is a flood designed according to a design standard. Design standards are based on objective needs. With the size of the project, tasks, nature, etc., the design standards are not the same. However, due to the long-term and relatively short-term accumulation of hydrological data, the hydrological laws it reflects have not been recognized enough under special circumstances. Therefore, in order to carry out economic comparison and check hydraulic structures
