Study of Hydraulic Jump Length Coefficient with the Leap Generation by Canal Gate Model

The length of hydraulic jump is a parameter needed to design the stilling basin dimension in the downstream of the weir or the other water structure in the river and channel. To determine the hydraulic jump length was needed function with some flow variables associated with the hydraulic jump phenomenon. One of variable to obtain the hydraulic jump was the hydraulic jump length coefficient ( Cj). A study to determine the hydraulic jump length coefficient was conducted experimentally in laboratory. The data of experiment result was analyzed by regression technic. The results are the hydraulic jump length coefficient in fixed value and function with variable is a ratio of upstream and downstream depth of the the hydraulic jump.
