Abstract: Replacing the sprinklers on a center pivot irrigation system with perforated, polyflex tubes converts a sprinkler system to a trailing tube system. Such a system is similar to a traveling trickle irrigation system. The ...

Abstract: The concept of treating soil matrix as a bundle of capillary tubes was used extensively in the analytical description of hydraulic conductivity of unsaturated soils. Such a concept has seldom been used in the development ...

Abstract: Grid networks, consisting of nodes and line elements, are often used in porous media flow simulation. An important step in the simulation process is the quantification of the line element conductivity when the pressure or ...

Abstract: The Mein‐Larson extension of the Green‐Ampt infiltration model is extended further to analyze the infiltration process under a variable rain on a covered natural soil. Such a condition represents the infiltration under ...

Abstract: A three‐dimensional Green‐Ampt analysis is developed, and the infiltration capacity curve for a three‐dimensional infiltration model is presented. The infiltration‐capacity curve represents the time distribution of ...

Abstract: In the traditional analysis, the radius is defined as a constant radial distance beyond which the aquifer is undisturbed by the pumping of water from a well. In the real world, the radius is a transient variable. Its value ...

Abstract: Trail tubes are perforated polyethylene hoses used to replace sprinklers on moving irrigation machines. Trail tube irrigation system is similar in concept to a traveling drip irrigation system. A catenary trail tube is a ...

Abstract: Transport of water-soluble agrichemicals has been intensively studied in the past few years for its use in the protection of ground water from contamination. An accurate description of solute transport is largely based on ...
