Irrigation and Drainage Systems Engineering is the one of the High Impact journal in Irrigation Management related field. Irrigation is the artificial exploitation and distribution of water at project level aiming at application of water at field level to agricultural crops in dry areas or in periods of scarce rainfall to assure or improve crop production. The goal of irrigation management is to use water in the most profitable way at sustainable production levels. For production agriculture this generally means supplementing precipitation with irrigation. In recent years we have seen declines in groundwater levels, almost statewide. Much of the State of Nebraska is considered fully or over-appropriated. This means that in those over-appropriated areas there will be no new development of irrigated acres.
