Abstract: As the flow expands at expansions, generation of turbulence by shear layers results in the dissipation of energy of the mean flow. Based on simplified momentum equations, this head loss was previously estimated to be ...

Abstract: This paper presents the results of an experimental study on the hydraulics of simple Denil fishways. For the Standard Denil, the characteristic velocity profile that exists in the fully developed flow region is found. A ...

Abstract: A steady uniform flow of high concentration sand‐water mixture was recirculated in a flume using a progressing cavity pump. The flume was set on a slope of 28.6%. A specially designed volumetric flow sampler was used to ...

Abstract: This paper presents the results of a laboratory study on flow past cylindrical piers placed on smooth, rough, and mobile beds. Experimental results are presented on the flow in the plane of symmetry, including the frontal ...

Abstract: The results of a study on the effect of ice cover on oil slicks contained by booms in rivers are presented. Experimental observations on velocities in the oil slick obtained by laser doppler anemometry are found to agree ...

Abstract: Based on the results of an experimental study on the diffusion of bluff turbulent wall jets in finite depth tailwater in a wide channel, it has been found that the transverse expansion of the jet depends strongly on the ...

Abstract: The results of an experimental study on the erosion of sand beds by plane water wall jets with minimum tailwater is presented. A comparison is made with the erosion caused by the corresponding deeply submerged water wall jet.
