Abstract: Center-pivot laterals are characterized by important friction loss, so therefore the energy consumption is also significant. In this paper, a new, particularly simple, equation is derived to solve explicitly the economic ...

Abstract: Analytical equations for direct hydraulic analysis of a multidiameter center-pivot lateral with and without an end gun were developed. The pressure head profile along the multidiameter center-pivot lateral is described by ...

Abstract: A simple and low-cost flow-measurement method for the field calibration of weirs is described. With this method, accurate estimations of the flow rate over a weir can be made on the basis of volumetric flow measurements ...
