Abstract: Hydraulic jump formed in abruptly expanding channels was experimentally studied. The study includes both horizontal and slopping channels. S-jump formed at different expansion ratios was studied under different flow conditions. Jump characteristics include sequent depth ratio, jump length ratio, and efficiency. Results show that the S-jump has a less sequent depth ratio compared to the classical jump and almost a similar jump length at high expansion ratios. Also the S-jump is more efficient compared to the classical jump and efficiency increases with the decrease of the expansion ratios. Prediction models for computing the jump characteristics have been presented. The sequent depth ratio prediction model has a simple format similar to the well-known Belanger equation "Chow [1]" for classical jump with modified Froude number. The modified Froude number includes abrupt expansion and bed slope effects. Experimental data from other sources are used to calibrate and verify the developed model. Prediction models for other jump characteristics show good agreement with the present and published data.
