实测降雨资料推求小流域洪峰探析

Analysis on Deriving Flood Peak in Small Watersheds Using Measured Rainfall Data

摘要:

以日照市三庄河小流域为例,通过实地调研、数据分析,利用2024年某场降雨实测资料,采用瞬时单位线法,推求小流域洪峰流量,对洪水进行复盘,倒推产汇流规律,为科学设置预警阈值,优化山洪灾害防御预案和河道防御洪水方案提供参考。

Abstract:

Taking the Sanzhuang River small watershed in Rizhao as an example, this paper uses the instantaneous unit hydrograph method to derive the flood peak discharge of the small watershed based on field research, data analysis, and measured rainfall data of a certain flood event in 2024. It conducts a review of the flood and infers the runoff generation and confluence laws, so as to provide references for scientifically setting early warning thresholds, optimizing mountain flood disaster prevention plans and river flood control schemes.
