Maximum sprinkler irrigation runtime without runoff

This article covers the practical solution to the equation developed by Hung & Krinik (1995) for determining the maximum sprinkler irrigation runtime. The authors compiled and analyzed the test data from the United States Natural Resources Conservation Service (USNRCS) and produced a series of curves representing the relationship between the maximum sprinkler irrigation runtime and the sprinkler precipitation rate for five types of soil.The curves can be used to determine the maximum sprinkler runtime for a selected or a calculated sprinkler precipitation rate for five types of soil. The application of the results from this paper will prevent sprinkler irrigation water runoff.
