Available in PDF, EPUB and Kindle. Book excerpt: The discovery of toxic pollution at Love Canal brought ground water contamination to the forefront of public attention. Since then, ground water science and modeling have become increasingly important in evaluating contamination, setting regulations, and resolving liability issues in court. A clearly written explanation of ground water processes and modeling, Ground Water Models focuses on the practical aspects of model application. It: examines the role of models in regulation, litigation, and policy development; explains ground water processes and describes specific applications for models; presents emerging technologies; and offers specific recommendations for better use of ground water science in policy formation.

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation research, three modeling tools have been developed to help quantify the complex processes of integrated surface- and ground-water systems in an area under significant agricultural development of Nebraska. To evaluate irrigation effect on stream depletion for the Lower Platte River (LPR) basin, a regional three-dimensional, transient groundwater-flow model is established with MODFLOW. A simplified and more efficient solution has been developed to estimate the stream depletion rate by re-using the flow coefficients of the baseline run. The flow equation is linearized because the head coefficients become constant between solver iterations. The tool has been successfully applied to the LPR model. The results show that the stream depletion analysis tool can reduce the numerical errors produced in the conventional method and improve the computational efficiency. The second modeling tool is a cross-section based streamflow routing (CSR) package for MODFLOW to simulate the streamflow and the interaction between streams and aquifers for the stream with a width larger than the MODFLOW grid size. In the CSR package, streams are divided into stream segments which are formed by two consecutive cross-sections. A rapid algorithm is used to compute the submerged area of the MODFLOW grid. Stream-aquifer seepage is treated as lateral flow in the streamflow routing computation with the Muskingum-Cunge method or mass conservation method. A hypothetical problem was established to test the capabilities of the CSR package with steady- and transient-state models. The third part of this dissertation aims to quantify the impacts of natural processes and human activities on ground-water dynamics in highly agricultural areas by developing an integrated surface-ground water model (ISGWM). In ISGWM, SWAT and MODFLOW are linked by a soil water module (SWM), which is developed based on a non-iterative solution of the 1D Richards equation. SWM explicitly represents infiltration, soil evaporation, unsaturated water flow, root water update, and lateral drainage. Taking advantage of the simulation capacities of these SWAT, MODFLOW and SWM, ISGWM can simulate the physical hydrologic processes in three domains and their interactions. The model has been successfully applied to the Johnson Creek watershed, which is located within the Lower Platte Basin.

This book was released on 2019 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historic placer mining operations along the Middle Fork John Day River (MFJD) north of Galena, Oregon have left the MFJD channel straightened, incised and lacking in riverbed structure. This lack of riverbed structure makes this stretch of the MFJD poor habitat for trout and migrating salmon. In order to restore this stretch of the MFJD to better serve aquatic species, Inter-Fluve Inc. (IF), United States Forest Service (USFS) and The Freshwater Trust (TFT) will be performing restoration to both the MFJD channel as well as Bear Creek, a tributary of the MFJD. The proposed restoration work will consist of re-routing of the MFJD and Bear Creek, re-meandering of the MFJD and construction of riverbed structure throughout the MFJD.In preparation for this proposed restoration, the connectivity of groundwater and surface water throughout the reach must be assessed. The main focus of this groundwater and surface water connectivity assessment will be to characterize how wetlands located along the reach interact with surface water features via groundwater. Characterizing the connection between groundwater and surface water will aid in determining the potential risk of proposed restoration having negative impacts on wetlands located along the reach. In order to fully characterize the groundwater and surface water connectivity at the site, a monitoring plan focused on geologic, hydrogeologic and hydrologic characteristics was implemented. Data obtained from site monitoring was used to support a groundwater model for the site. This groundwater model was used to make predictions of how proposed restoration would impact the site wetlands.Steady state and transient groundwater models of observed conditions calibrated relatively well producing low error values. Groundwater models revealed that initial restoration performed on Bear Creek has had a negative impact on the site wetlands. When all proposed restoration work is modeled, an overall increase in wetland water elevations is predicted throughout most the wetland area. Water elevations near the abandoned Bear Creek channel however, show a decrease in water elevation when all restoration work is implemented. This decrease in water elevation only occurs between May and July; modeling of July through October in this area show an increase in water elevation levels. Overall when all proposed restoration is completed, the site wetlands and entire site in general will benefit in terms of higher water elevations, especially during base flow conditions.
