Effects of Upward Seepage on Depth of Scour Hole Downstream of Free Falling Jets Under Constant Tail Water Depth
rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. Scour downstream of this structure can lead to failure. Over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...
متن کاملnoncohesive sediment scour downstream of an apron
the effect of grain size, tailwater depth and grain froude number on local scour caused by submerged horizontal jets issuing below a sluice gate was investigated. noncohesive sediments with two gradations downstream of a horizontal apron were used in the experiments. the experiments were carried out at different inflow froude numbers and a range of tailwater depth from low to high submergence. ...
متن کاملScour Downstream of a Rough Rigid Apron
A series of experiments was conducted to investigate the erosion behaviors of the noncohesive sediments downstream of smooth and rough aprons. A total of 33 tests were carried out with five different roughness conditions (k =0, 1, 1.85, 3.35 and 5mm) in a flume 0.5m wide, 0.6m deep and 9m long. For each run, s measurements were taken of the scour-hole profiles at the asymptotic or equilibrium s...
