Evaluation of Water Application and Trafficability of Center-Pivot Irrigation Systems
Spray distribution obtained from a single stationary sprinkler head was used to determine the effects of reduced operating pressure on evaporation loss, uniformity of application, sprinkler spacing, and application rate of a center-pivot sprinkler irrigation system. Patterns obtained from a spray nozzle, part circle sprinkler, 26 degree trajectory full circle sprinkler, and 6 degree trajectory full circle sprinkler were simulated to moving patterns. The 6 degree trajectory full circle sprinkler had uniformities comparable to the 26 degree trajectory full circle sprinkler with about 24 percent less evaporation loss and about seven percent less wetted diameter on the average of the four pressures. A recommendation for sprinkler spacing was made which would provide satisfactory sprinkler performances at reduced pressure. Application rates were much higher for the spray nozzle than the sprinklers.
