Preliminary Study on the Distribution Law of Flood Peak Modulus of Small and Medium Rivers in the Lianjiang River Basin
摘要
Abstract
Based on measured flood data of small and medium-sized rivers(200～3000km2)in the Lianjiang River Basin,The design flood is calculated from the design rainstorm in the area without data.Taking into account factors such as upstream and downstream,main and tributaries,and underlying surface conditions,and combining historical flood survey data,existing engineering design flood results,basic geographic information data,draw contour maps of flood peak flow modulus for small and medium-sized rivers in the Lianjiang Basin at different recurrence periods,and explore the distribution law of flood peak modulus.The results indicate that the flood peak modulus in the southern part of Ruyuan,the northwestern part of Yingde,the southern part of Yangshan,the central and southern parts of Liannan in the middle and lower reaches of Lianjiang River is relatively large,and attention should be paid to flood prevention process.The research results of this study can provide reference and decision-making basis for preventing floods in small and medium-sized rivers in the Lianjiang River Basin,and have certain reference significance for hydrological analysis and calculation,water conservancy and hydropower engineering planning and design in the Lianjiang River Basin.关键词
