- This paper introduces and discusses the basic concepts and structure of IHACRES model based on unit hydrograph principles. IHACRES模型以單位線為基礎,結構簡單、概念明確、優選參數少,在國外已被廣泛研究和應用,並認為是一個相當成功的流域水文模型。
- The developed rainfall-runoff models with unit hydrograph mainly focus on simulating surface runoff, only a small number of models can be used for subsurface runoff. 摘要過去發展之以單位歷線為主之降雨-逕流模式大多隻限於模擬地表逕流,對於地表下逕流之演算僅有少數幾種模式可資應用。
- In the linear perturbation Model(LPM),the ordinary lest squares (OLS) method is used in order to obtain the multi-regression cofficients (nonparametric unit hydrograph) of the conuolution summatron of the input and output departures. 在線性擾動模型(LPM)中,輸入和輸出離均差的卷積求和是採用最小二乘法(OLS)求解,以得到非參數單位線縱標即回歸係數。
