ESTIMATION OF GLOBAL IRRIGATION DISTRIBUTION UNIFORMITY

This work demonstrates the applicability of more generalized sluice gate equations to the design of baffle sluice modules. The generalized equations allow the module to be designed for any upstream head. These equations also offer additional understanding of the behavior of the baffle sluice module and demonstrate that the first baffle of the module is largely redundant. The constraint of having the minimum water level coincide with the crest of the first baffle has been removed. Through an optimization procedure, an alternative design method is suggested that will theoretically improve the performance of the baffle sluice module. Through this design technique, a module can be designed with any practical number of baffles. The effect of combined orificeweir flow and width of the module is also discussed.
