Optimal Conjunctive Use of Surface and Groundwater with Recharge and Return Flows: Dynamic and Spatial Patterns.

The article presents a paper which was presented during the "New Frontiers in Water Resource Economics" session of the annual meeting of the Allied Social Sciences Association on January 5-7, 2007 in Chicago, Illinois. The authors derive the efficiency price patterns for a model of conjunctive water management. For optimal water resource use, the shadow prices of irrigation water are needed, taking into account canal return flows, conveyance losses and groundwater recharge.
