A 54 year (1930-1983) precipitation record was used to determine the future probability of drought occurring in a specific location under a given set of conditions in Virginia. Econometric models developed by Taylor, et al. (1985) were used to conduct the economic analysis. Econometric models for various ranges for center pivot, traveling gun, big gun, and portable pipe irrigation systems were utilized in the procedure. The developed procedure was applied to the Pamunkey River area in Eastern Virginia. Projections on cumulative irrigated acreage, pumping capacity, and seasonal water use were produced.x, 273 leavesapplication/pdfenIn CopyrightLD5655.V855 1985.V444Irrigation farming -- Economic aspects -- VirginiaIrrigation farming -- VirginiaThesis
