Stream depletion factors, Arkansas River valley, southeastern Colorado; A basis for evaluating plans for conjunctive use of ground and surface water

The Arkansas River valley is a stream-aquifer system that consists of the Arkansas River and the associated valley-fill deposits. The hydrology, geology, and water-resources development in the valley have been described by Moore and Wood (1967). The history of delivery of irrigation water by canals indicates that the supply has been inadequate during some seasons and some years. The shortage can be reduced by carefully designed conjunctive use of ground and surface water. An analog model of the Arkansas River valley in Colorado was constructed to facilitate such designs (Moore and Wood, 1967).
