Water harvesting techniques are being studied to determine its potential as an alternative reclamation practice. To assist planners and decision makers in evaluating the water harvesting potential, a procedure is developed by which precipitation and its distribution are simulated and incorporated with a runoff model to forecast the long term availability of harvested water. The output from the stochastic precipitation model and statistically- derived runoff model provide a simulated 100 years of annual precipitation and runoff events. Two reservoirs were designed and evaluated separately using varied seasonal irrigation demands. The sensitivity analysis, of varying the demand, revealed yearly water reliability decreased as the total seasonal irrigation demand approached the mean annual runoff. It was also shown that an appropriate reservoir size could be chosen using the probability distributions of the number of dry reservoir days and the number of days the reservoir overflows.Type

Hydrogeology and simulation of ground-water and surface-water flow in Pinal Creek Basin, Gila County, ArizonaAcidic water with elevated concentrations of metals has contaminated a stream and alluvial aquifer in a mining district near Globe, Arizona. The contaminated aquifer is a narrow layer of unconsolidated alluvium along Miami Wash and Final Creek. The purpose of this study was to evaluate the hydrogeology of this area and to simulate the surface- and ground-water flow. The alluvium overlies basin fill which extends throughout most of Final Creek basin. Together, the alluvium and basin fill comprise the primary aquifer in the basin. Horizontal hydraulic conductivities have been estimated to be about 200 m/day in the alluvium, and average linear, ground-water flow velocities are on the order of 5 m/day. Flow was simulated by a three-dimensional, finite-difference, ground-water flow model that maintains a streamflow water budget. Steady-state simulations were performed and adjusted to represent average annual water budget conditions. The transient simulation period covers September 1984 to April 1989, for which considerable data were available for model calibration.

Simulative models for the analysis of ground-water flow in Vekol Valley, the Waterman Wash area, and the Bosque area, Maricopa and Pinal Counties, ArizonaSimulative ground-water flow models were developed for Vekol Valley and the Waterman Wash and Bosque areas for use in evaluating alternatives for developing a ground-water supply for the Ak-Chin Indian Community. Annual recharge to the first two areas is negligible compared to the quantity of water in storage and that proposed to be pumped. The models are based on a three-dimensional, block-centered. finite-difference scheme. The Vekol Valley model was calibrated for steady-state conditions and the Waterman area model for steady-state and transient conditions. An uncalibrated storage-depletion model was developed for the Bosque area. Sensitivity of calibrated heads to changes in transmissivity was also investigated. Simulated water levels for transient conditions in the Waterman Wash area average within 8 feet of measured values for 15 years of analysis and within 15 feet for 24 years. Water-level declines simulated by the Waterman Wash area model average within 17 feet of those measured during 1951-75.
