Placement of Lateral intake in Order to Control Incoming Sediment

The diversion flow pattern is quite 3-D and non-uniform. In general, flow diversion occurs either naturally like braided rivers or artificially like lateral intakes. According to the performed investigations, the intake location affects the rate of water intake and sediments entry into the diversion channel. The use of lateral intake along with diversion channel is one method of providing water from river. Given the fact that most rivers are in nature in their meander state, so determining the position and angle of water intake is very important. Since the main purpose of lateral intakes is to facilitate water transfer without sediments and most of the rivers are zigzagged through their path, therefore, more researches on the location of the lateral intake and its angle on the arc paths it seems necessary. The results showed that the effective parameters in sediment deviation include: Discharge ratio, Flow conditions [Froude number], Sediment load [Bed load and Suspended load], Water intake location [On the channel arch], Deviation angle, Input threshold and Submerged plates that researchers examined impact of some of them to choose the best the intake location.
