Hibbs and published by . This book was released on 1993 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive hydrogeological investigation was conducted within the Colorado River alluvial aquifer of south-central Texas. The study characterized bank storage interactions caused by irrigation and flood releases from the Highland Lake Reservoirs above Austin, and evaluated the underflow criterion for managing water resources in the Colorado River Basin. The hydrodynamics of the bank storage effect were studied in an integrated tracer and modeling investigation. Variations in dissolved solids between Colorado River water and ground-water created ideal conditions for analysis of stream/aquifer interaction during natural and artificial floodwaves. Two sites were instrumented with observation well and stream-stage recorders. At each site, head, temperature, and chemical data were collected during low-flow, mid-flow, and peak-flow conditions. Significant variations in stream stage and reversals of hydraulic gradient in the adjoining alluvial aquifer were created by releases of water from upstream reservoirs both in response to storm events and for irrigation by downstream users. Aquifer head responded relatively rapidly to changing stream stage during controlled reservoir releases, but tracer (both solute and heat) breakthrough curves were generally not observed even for observation wells very close to the Colorado River. The water table response lagged behind the average head response in the observation wells. These results are postulated to occur as a result of elastic head response in the shallow, unconfined aquifer to rapid changes in stream stage, analogous to the delayed yield effect in an unconfined aquifer during the early stages of pumping. The coupled-process numerical model HST3D was used to develop confined and unconfined aquifer models to simulate the stream/aquifer response. Although the aquifer is clearly recognizable as an unconfined aquifer, the confined aquifer model gave a superior simulation. Both modeling and field data support the hypothesis of elastic head recovery response in the unconfined aquifer. The underflow criterion was evaluated as a legal provision to prevent stream depletion of the Colorado River by high capacity alluvial wells. Study results indicate that the Colorado River alluvial aquifer is not an underflow-dominated system. Even so, site-specific investigations showed that temporally varying underflow zones sometimes exist very close to the river. In more than 90% of the floodplain, data are not available to identify these zones. Beyond the underflow zones, the hydraulic connection between the Colorado River and the alluvial aquifer may extend thousands of feet into the floodplain. Therefore, the potential for stream depletion by wells distant from the underflow zone(s) is great. Study results suggest that the underflow criterion will not be effective as a provision to prevent stream depletion of the Colorado River as the floodplain undergoes agricultural and urban development.

Available in PDF, EPUB and Kindle. Book excerpt: A new option for Local Time-Stepping (LTS) was developed to use in conjunction with the multiple-refined-area grid capability of the U.S. Geological Survey's (USGS) groundwater modeling program, MODFLOW-LGR (MF-LGR). The LTS option allows each local, refined-area grid to simulate multiple stress periods within each stress period of a coarser, regional grid. This option is an alternative to the current method of MF-LGR whereby the refined grids are required to have the same stress period and time-step structure as the coarse grid. The MF-LGR method for simulating multiple-refined grids essentially defines each grid as a complete model, then for each coarse grid time-step, iteratively runs each model until the head and flux changes at the interfacing boundaries of the models are less than some specified tolerances. Use of the LTS option is illustrated in two hypothetical test cases consisting of a dual well pumping system and a hydraulically connected stream-aquifer system, and one field application. Each of the hypothetical test cases was simulated with multiple scenarios including an LTS scenario, which combined a monthly stress period for a coarse grid model with a daily stress period for a refined grid model. The other scenarios simulated various combinations of grid spacing and temporal refinement using standard MODFLOW model constructs. The field application simulated an irrigated corridor along the Lower Rio Grande River in New Mexico, with refinement of a small agricultural area in the irrigated corridor. The results from the LTS scenarios for the hypothetical test cases closely replicated the results from the true scenarios in the refined areas of interest. The head errors of the LTS scenarios were much smaller than from the other scenarios in relation to the true solution, and the run times for the LTS models were three to six times faster than the true models for the dual well and stream-aquifer test cases, respectively. The results of the field application show that better estimates of daily stream leakage can be made with the LTS simulation, thereby improving the efficiency of daily operations for an agricultural irrigation system.
