Pressure Head Profile of Linear-Move Sprinkler Irrigation Laterals: Analysis, Equation and Profile Patterns

An equation that expresses lateral pressure as an explicit function of distance from the lateral inlet is derived for linear-move sprinkler irrigation systems. The equation takes into account the effects of both field slope and span geometry on lateral pressure. The proposed equation is not intended for predictive use. Instead, it is used here in an additional evaluation of the validity of the unique pressure profile variability patterns, of...
