investigation of spur dike and submerged vanes on dividing streamline at lateral intakes

flow pattern at lateral intake using a spur dike and submerged vanes

flow passing through lateral intakes and channel junctions is turbulent. sediment flow and bed forms areaffected by these flow patterns and vice versa. in this research, a laboratory study was carried out toexplore a possible method for sediment control for a set of submerged vanes and a single spur dikesimultaneously. since a larger portion of the near-bed flow was diverted, the intake receive...

Calculation of Optimum Dimensions and Array of Submerged Vanes at Intakes Using the Feasible Direction Method

In recent years, installation of plates in canal beds have been considered for sedimentation control and bed load reduction at canal intake. These planes, called submerged vanes, are different in dimensions. They are installed at intakes in-group with reasonable distance from each other. Presence of these vanes at intakes initiate transverse shear stress on river bed and causes sediment transpo...

Investigation of Submerged Vanes Array for Sediment Control at Intake Using a Physical Model

application of submerged vanes for sediment control at intakes from irrigation trapezoidal channels

construction of the intake structures to divert some portion of flow water from a main channel causes some variations of flow conditions at the intake entrance. these variations cause the reinforcement of the eddy flow and sedimentation in the bank of the intake. an effective measure to control the entry sediment is the use of submerged vanes. most of previous studies in this regards have been ...
