Title:Hydraulic jump type stilling basins for Froude number 2.5 to 4.5

Hydraulic jump type stilling basins are used to prevent the detrimental effects of the supercritical flow velocity on the stability of the channel. Laboratory investigations were conducted for both the ordinary and the forced hydraulic jumps on a horizontal floor in the Froude number range of 2.5 to 4.5. Data from the ordinary hydraulic jump correlate well with the theory and other published data. A set of appurtenances (baffle blocks and an end sill, basin L) for forced hydraulic jump was found to perform satisfactorily. Comparison of the test data from this basin with corresponding data from the ordinary hydraulic jump showed that the required tail-water depth can be decreased, energy loss can be increased, and the jump can be formed in a much shorter basin. A theoretical relationship has also been developed to predict the turbulent pressure fluctuations in the stilling basins. Hydraulic design of stilling basins for the Froude number range of 2.5 to 4.5 can be accomplished with the aid of the criteria developed in the report.
