Mixed Integer Programming Model for Flood Hydrograph Amplification at Same Frequency
摘要
Abstract
When the relationship between peak and volume of design flood is poor,the same frequency amplification of design flood hydrograph will have significant abnormalities.In this paper,a mixed integer programming model with the same frequency amplification of the design flood hydrograph is constructed,in which,the flow of each time period of flood hydrograph is taken as the decision variable,the smoothness function of time series is proposed as the objective function,the design flood peak flow and design flood volume at different periods are taken as constraints,and for the first time,the same direction constraint of fluctuation is added to ensure that the design and typical flood hydrograph have similar patterns.The case study shows that,when the relationship between design flood peak frequency and volume is not coordinated,the design flood hydrograph calculated by the model in this paper is smooth,and there is no intersection between the frequencies,which is similar to the typical flood hydrograph,especially in the period near the flood peak.The research results provide a new and feasible method for the same frequency amplification of the design flood hydrograph.关键词
