Hydraulic jump energy dissipation is a form of energy dissipation frequently used in hydraulic engineering. Many scholars at home and abroad did a lot of research on hydraulic jump. In engineering practice people found that hydraulic characteristic values of c-type fold slope hydraulic jump and the standard method for calculating the value has a bigger difference. Aiming at the characteristics of hydraulic jump with c-type fold slope the experiment was carried out, and combined with the dimensional analysis and numerical analysis method, obtained the calculation formula for the water depth after c-type fold hydraulic jump and hydraulic jump length under the slope angle as the parameter, and using flume test data and practical engineering hydraulic model test was verified. The results showed that the calculation error of the formula less than ±12%, therefore. It can provided some reference for engineering design.
