IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Hydraulic jump in a gradually expanding channel with different divergence angles
Author : S M Kashefipour and M. Bakhtiari
This paper describes the hydraulic jump characteristics in a gradually expanding channel. The experiments were carried out in a flume with 12 m length, 0.25 and 0.5 m width and depth respectively. Five physical models were built based on the divergence angles, including 5, 12.5, 15, 22.5 and 25 degrees and were fixed in the flume. Jump was controlled to be occurred along the
structure. The measured characteristics of the hydraulic jump for different discharges and Froude numbers were compared with each other and with the corresponding values measured for the classical jump. The results showed that the relative sequent depths and the relative length of the jump decrease, whereas the relative energy loss increases with increasing the expansion angle. The maximum relative energy loss was obtained for the angle of 25 and it was about 55% more than the relative energy loss for the classical jump with a Froude number of 4.
