| Abstract: | A fuzzy nonlinear differential dynamic model, FNLDDM(n,1), of watershed confluence is established and its nonliear and fuZZy coefficients are optimized by combining flexiplex of nonlinear programming with the method of least squares of linear model in which importances of deviations between observed and forecasted flows can be taken into account of.The model FNLDDM(2,2)is studied in detail and is applied to the calculation of confluence of Qinghe reservoir watershed. Satisfactory results have been attained. |
