Optimum Water Intake Angle from Main Channel with Slopping Bank
Author(s):
Abstract:
The main goal of hydraulic engineers is to design a water intake to deliver the maximum flow discharge with the minimum sediment entry. The optimum delivery angle, three dimensional flow pattern, sedimentation and sediment entry are the major parameters which must be considered at lateral intakes. According to the available literature, in previous studies the optimum water intake angle from main channel with slopping bank and suspended load had not been considered. Therefore, in this study, different sediment and hydraulic experimental tests were carried out at 30, 45, 60 and 90 degrees water intake installed at the bank of a trapezoidal channel. The effects of stream tube dimensions, secondary current and suspended sediment delivery into the intake were assessed for determining the optimum delivery angle. Finally, by analysis of these parameters, the 30 to 45 degrees angles were suggested to be the optimum delivery angles from a main channel with inclined bank.
