| Abstract: | The choice and design for type of discharge energy dissipation is one of the key technolog- ical problems, which is for the construction of high dam in gorge region at home and abroad. Under- flow for energy dissipators with sudden expansion and abrupt drop is a new type of energy dissipator.With the consideration of influenced by sudden expansion and abrupt drop, theory relationship for conjugate depths of hydraulic jump with is proposed firstly. The computational relationship for conju- gate depths of multiple submerged jets is obtained also, which has very important theoretical guiding significance. |
