Research on flow calculation method of improved synthetic unit hydrograph of Guangdong
摘要
Abstract
In order to study the design peak flow calculation method of medium and small basins in Guangdong, improved synthetic unit hydrograph based on Guangdong synthetic unit hydrograph improvement was put forward. It was combined with characteristics of the present triangular unit hydrograph models and simplified analysis results of Guangdong synthetic unit hydrograph by considering the minimum sum-of-squared differences. The improved synthetic unit hydrograph was set up to establish formulas of the rising duration, base period and peak value. The design peak flow was calculated by loading improved synthetic unit hydrograph with the net rainfall list and taking influence line loading principle as lessons. Results show that the improved synthetic unit hydrograph has enough theoretic bases, and its calculation process is easy to master. Cases analysis results prove that, improved synthetic unit hydrograph method is reliable compared with comprehensive unit hydrograph method and rational formula method of Guangdong. It can be applied in the whole province after further verification.关键词
