Abstract: A differential approach is applied to multiple outlet pipes with constant and continuously variable outflow. This approach simulates pressure distributions along uniform sprinkle and trickle irrigation laterals and manifolds, ...

Abstract: Analytical equations that characterize hydraulics of center‐pivot laterals with and without end‐gun sprinklers were developed. The equations include computation of pressure‐head distribution; pressure‐head loss; and maximum, ...

Abstract: Practical methods for land grading design of a plane surface for rectangular and irregularly shaped fields based on a least squares analysis are presented. The least squares procedure leads to a system of three linear ...

Abstract: A volume balance approach to determine the parameters of the Kostiakov or modified Kostiakov infiltration equations in border and furrow irrigation is presented. The approach requires measured data from the advance phase, ...
