“温比亚”与“利奇马”台风期弥河流域降雨分布对比研究

Comparative study on rainfall distribution in Mihe River basin during typhoon “Wambia” and “Lichma”

2018年、2019年,山东连续遭受台风影响,其中台风"温比亚""利奇马"过境引起的强降雨使弥河流域遭受重大洪灾。本文采用实时报汛数据,从全流域及上、中、下游的降雨空间分布、降雨强度、主降雨时间以及谭家坊区间降雨产流规律等方面对弥河流域两次台风进行对比分析,为今后弥河流域及相似流域水资源开发、洪水调度等提供基础研究资料。

In 2018 and 2019,Shandong was continuously affected by typhoons,and heavy rainfall caused by the transit of typhoons"Wambia"and "Lichma"caused severe floods in the Mihe River basin. In this paper,the real-time flood forecast data are used to make a comparative analysis of two typhoons in Mihe River basin from the aspects of rainfall spatial distribution,rainfall intensity,main rainfall time and rainfall runoff generation law in Tanjiafang interval,which provides basic research data for water resources development and flood dispatching in Mihe River basin and similar basins in the future.
