设计洪水是未来洪水的预测,是水利工程设计的依据,为流域规划设计中的重要资料。它的内容主要包括洪峰、洪量过程线型式和设计标准,由于各个河流特性和工程性质大小的不同,其中各要素反映在各水利工程规划设计中所起的作用和所占的重要性,亦各有异。汉江中下游受洪水威胁严重,当遇较大洪水时,不仅会造成大量生命财物毁灭性的损害,并可直接威胁到武汉市的安全,影响南北交通运输,因此设计洪水的确定,也就更显重要。
Design flood is the prediction of future flood, is the basis of water conservancy project design, and is an important data in basin planning and design. Its content mainly includes flood peak and flood discharge process line type and design standard. Due to the different characteristics of rivers and the nature of project, each factor reflects the role and the importance of each element in the planning and design of each water conservancy project. Different. The middle and lower reaches of the Han River are seriously threatened by floods. In the event of a large flood, not only will they cause massive devastation of lives and property, but they will also directly threaten the security of Wuhan and affect the transportation between North and South. Therefore, the determination of design floods Significantly important.
