In view of the peaked and fat-tailed characteristics of financial return data distribution and its effect of clustering fluctuation and especially the "leverage effect" of fluctuation on VaR estimates and some efficiencies when estimating VaR with various assumptions of return data distribution,a semi-parameter approach based on EGARCH-VaR model is developed.

The result show that the position of free surface is higher because of frusta of brake, especial obvious in the head of frusta of brake; flux coefficient and pressure on dam are quite influenced by type of frusta and 3 A type frusta of brake relative to 2 type frusta of brake has bigger flux coefficient and smaller pressure on dam; Obvious influence of ability of discharge flow for different ratio of thickness of frusta and breadth of brake and pressure on dam reduces with increasing ration of thickness of frusta and breadth of brake, while bigger flux coefficient is obtained when tlb = 0.2.(7)The 3D free surface turbulent model established in the paper is comparatively well and truly simulates 3D flow over spillway with frusta of brake and series waterpower computation can be completed aim at different type of dam, type of frusta and disposal on the dam and different water height on peak of
