  The pressure head profile of an irrigation lateral is a function of the hydraulic and geometric characteristics of the lateral and its slope. Slope effects on pressure variability along a lateral are typically limited. However, for a lateral with a spatially invariant parameter set well-defined relationships can be discerned between lateral slopes and the spatial patterns of the lateral pressure profiles. Thus, a comprehensive understanding of these relationships can be useful in the evaluation of lateral hydraulic simulation models and design recommendations. Existing studies have examined slope effects on the locations of pressure head extreme, along a lateral, in the context of hydraulic design of laterals. This paper presents a comprehensive analysis of slope effects on lateral pressure head profile patterns. The monotonic properties, with respect to d.. Read More»
