E. A. MOULDERand C. T. JENKINS: Analog-Digital Models of Stream-Aquifer Systems. Ground Water, Vol. 7, No. 5, p. 19-24, Sept.-Oct. 1969.6p., 8 fig. The best features of analytical and digital computers were combined to make a management model of a stream-aquifer system. The analytical model provided a means for synthesizing, verifying and summarizing aquifer properties; the digital model permits rapid calculation of the effect of watermanagement practices. Given specific management alternatives, a digital program can be written that will optimize operational plans of streamaquifer systems. The techniques are demonstrated by application to a study of the Arkansas River valley in south-eastern Colorado. Many streams are hydraulogically connected to large ground-water bodies in valley-fill deposits adjacent to and underlying the stream. In the Western United States many alluvial valleys are irrigated both by surface water and by ground-water. The Arkansas River valley in south-eastern Colorado is typical of such systems. The average yearly supply of surface water is about equal to the crop requirements, but because there are few surface storage facilities severe surface-water shortages occur during the latter part of the growing season. The ground-water reservoir offers a means of regulating the supply. Since about 1950, irrigators have installed 1200 large-capacity wells in the valley to supply late-season deficiencies.
