Abstract: The volume balance model was modified to allow explicit solution for the advance distance in surface irrigation. In a dimensionless formulation, the advance distance equation was compared with the correct form of the Hall ...

Abstract: Simulation of sloping furrows with free outflow was accomplished to assess the effect of inflow pattern on maximum application efficiency. For five inflow hydrograph patterns, the maximum application efficiency was predicted ...

Abstract: Sloping borders with free outflow were studied to determine the effect of inflow hydrograph shape on maximum application efficiency. A zero-inertia model describing the movement of water along the border run with infiltration ...

Abstract: Friction head loss equations and friction correction factors were evaluated and compared to field observations collected from thirty center pivots with laterals made of PVCs. The friction head loss equations include ...
