how to calculate hydraulic jump. For overflow discharges larger than the design discharge it may be acceptable to tolerate some erosion and damage ie. Consider sections 1-1 and 2-2 before and after the hydraulic jump.

V1 average flow velocity before the hydraulic jump ftsec. Q V 1 Y 1 B V 2 Y 2 B F 1 V 1 g Y 1 05 F 2 V 2 g Y 2 05. This high water level can be used for irrigation purposes.
The post jump Froude number F r2 will be less than 1.
V2 average flow velocity after the hydraulic jump ftsec. Or m for SI. Measure the depth of flows. Hydraulic jump in open channels can be attributed to rapidly varied flow where a significant change in velocity occurs from super-critical flow to sub-critical flow.
