DOWNLOAD EBOOKThis study was designed to meet the specific needs of the Environmental Protection Agency consistent with the interests and research goals of the ARS. The specific objectives of the study are: (1) to identify variables needed to predict effects of deep percolation, tailwater runoff, and lateral seepage on the quality of return flows. Includes evaluation of quantity and quality of various components of field water balance. (2) To define the effect of irrigation water management on the quality of runoff and deep percolation leaving the farm unit, and determine the reduction in both water and salt losses achievable through improved irrigation technology. (3) To identify mechanisms by which the salt load of return flow water is modified after it leaves the farm unit and moves toward the Colorado River; to attempt to determine the most practicable control methods for salt accretion. (4) To evaluate the experimental methods used in the above studies with regard to their applicability in other similar irrigated river valleys.

DOWNLOAD EBOOKThere are a multitude of research needs regarding irrigation return flow quality, but only the specific research needs required to undertake an effective control program are described. These research needs include irrigation practices, soil-plant-salinity relationships, leaching requirements, prediction of subsurface return flow, cultural practices, irrigation scheduling, treatment of return flows, economic evaluations, and institutional control methods.

DOWNLOAD EBOOKThe status of the National Irrigation Return Flow Research and Development Program is presented. Current research projects and future program development are discussed. The report represents the position of the Environmental Protection Agency (EPA) with regard to the development of effective controls on the quality of irrigation return flows. Program goals and milestones are outlined. A number of potential control measures are discussed. Improvements in the water delivery system, on-the-farm water management, and the water removal system are considered with respect to improving the quality of irrigation return flows and decreasing the degradation of receiving waters. Research and investigations are needed to evaluate the effectiveness of potential control measures. Demonstrations and educational activities will be required to overcome institutional, political, and legal constraints to water management reform.
