Abstract: Uniform distribution of water along a lateral or manifold is one of the primary objectives of a pressurized irrigation system designer. To design a system that will meet this objective requires establishing a relationship ...

Abstract: The economic design of microirrigation and sprinkler laterals requires the use of a combination of diameters of different lengths. The present practice is to solve the basic hydraulic equations using a trial-and-error ...

Abstract: Application of a remote sensing technique for estimating regional evapotranspiration requires extrapolation of instantaneous values to periods on the order of 1 day or more to be of practical use. A method for developing ...

Abstract: A prototype raster geographic information system (GIS) coupled with a decision support submodel for agricultural nitrogen nonpoint source pollution analysis is presented herein. This analysis is an extension of the ...

Abstract: Nondimensional runoff curves useful in the design of reuse systems are presented for free outflow irrigation borders. Pertinent open channel variables affecting runoff in border irrigation, including inflow rate, surface ...

Abstract: An analytical solution for a trickle lateral is presented which includes velocity head in the basic formulation. The relative error when neglecting velocity head is greater for laminar than for turbulent flow. However, the ...

Abstract: A procedure is presented for designing a system to reuse runoff from free outflow irrigation borders. Runoff volumes are obtained using four dimensionless variables and runoff curves developed with a zero‐inertia mathematical ...

Abstract: Agricultural water duties have historically been used to settle al‐locational disputes, adjudicate water basins, size canals, and schedule irrigation. The Arizona Department of Water Resources is now using water duties to ...

Abstract: Field measurements of water and solute distribution from a point source were made using the gravimetric method. The variables affecting water and solute distribution, including application rate (1.5, 2.0, and 2.5 L/h), ...
