Technical Abstract: Center pivot sprinkler irrigation is increasing in popularity in the Pacific Northwest due to the low labor requirement and ability to irrigate large fields. The main problem associated with pivots continues to be the inherently high application rates and tendency for runoff and erosion on the medium textured soils and rolling topography. Recently developed sprinklers or spray heads can produce high application uniformity with controlled drop sizes and medium sized pattern widths at medium to low pressures. A method is presented to predict the average and peak application rates at any point along a center pivot lateral for a particular type of sprinkler.
