Analysis of Flood Characteristics in Mountainous Watershed without Measured Data Based on Unit Line Method
摘要
Abstract
The derivation of design flood results in mountainous watersheds without measured hydrological data is related to the economic and applicability of watershed water resources development and utilization planning and engineering design.Taking Wenming Reservoir as an example,combined with the characteristics of the watershed above the reservoir dam site,this paper takes the nearby Lijiang Meteorological Station and Mujiaqiao Hydrological Station as reference stations,uses the unit line method and inference formula method to design and deduce the flood characteristics of the watershed,and compares and proves them with the design flood results of surrounding reservoirs.The research results indicate that the design flood results obtained by the unit line method are basically consistent with the distribution pattern of rainfall source rivers in mountainous areas,and the results are reasonable,feasible,and highly safe.关键词
