Abstract: Based on the model test of flood discharge on surface sluice, the effect of ski-jump energy dissipation of continuous bucket and differential bucket was analyzed. The results indicated nappe created by differential bucket aerated and crashed better in the air, both in the cases of design flood and check flood. The effect of differential bucket on energy dissipation was better. The plunge pool, which absorbed remainder kinetic energy of overflow effectively, satisfied dissipation requirements both at design level and check level. The scouring and destroy action to downstream bed was lighted greatly though energy dissipation in plunge pool.
