Finally, a broad discussion of sprinkler package options and the effects they have on system performance will be presented. Traditionally, the application rate is matched to the maximum soil intake rate. This involves determining the type of soil or soils that the system will be irrigating. Soils with like infiltration rates were grouped into Intake Families. Each of these soil Intake Families has a specific soil intake curve shown in Figure 1.
Soil intake curves are a good place to start when determining the maximum application rate.
Average application rates produced by different sprinkler packages, shown in Figure 2, illustrate that sprinkler packages with smaller wetted diameters have higher average application rates and vice versa. This text was extracted from the publication, L-908.
