Discussion on weight in fuzzy recognition unit hydrograph method
Wang Shumi · Jilin Water Resources · 2006
Many factors are considered in the selection of unit hydrograph: rain intensity,rainfall amount,influence rainfall amount in earlier stage of river basin,bottom water amount in river channel etc These factors influences the formation process of a flood,but their influence is not balance to run off and confluence,the consideration is not egual The consideration of weight for these factors is a difficult problem of fuzzy recognition unit hudrograph in the selection of unit hydrograph The paper puts forward the related analysis method to count all previous floods,the effect of these factors is quantitatively calculted for resolve the determination of weight vector in fuzzy recognition unit hydrograph
