Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Landsby Jonathon C. Goldman, (A.M.ASCE), Morrison-Knudsen Engineers Inc, San, Francisco, CA, USA,
Abstract: In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive water use may provide quantitative, qualitative and energy economies when compared with conventional water management alternatives. The practice of conjunctive management encompasses these resource development and operation strategies. Techniques for successful siting and operation of groundwater storage installations can benefit from recent developments in, and applications of, computer-based operation of surface water storage and conveyance networks. Despite technical and economic feasibility, obstacles to construction and operation of conjunctive management facilities are often legal and institutional. Recognition of benefits, problems and potential costs helps to identify suitable sites for physical demonstration of conjunctive management feasibility. Physically demonstrated technical and economic feasibility can be used as leverage in clearing the legal and institutional barriers to such water management.
