S. Department U.S. Department of the Interior and published by CreateSpace. This book was released on 2014-04-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A conceptual model of the hydrogeologic framework, geochemistry, and groundwater-flow system of the Edwards- Trinity and related aquifers, which include the Pecos Valley, Igneous, Dockum, Rustler, and Capitan Reef aquifers, was developed as the second phase of a groundwater availability study in the Pecos County region in west Texas. The first phase of the study was to collect and compile groundwater, surface-water, water-quality, geophysical, and geologic data in the area. The third phase of the study involves a numerical groundwater-flow model of the Edwards-Trinity aquifer in order to simulate groundwater conditions based on various groundwater-withdrawal scenarios. Resource managers plan to use the results of the study to establish management strategies for the groundwater system.

Book Synopsis Groundwater Sustainability by : Robert E. Mace
Download or read book Groundwater Sustainability written by Robert E. Mace and published by Springer Nature. This book was released on 2023-01-10 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will provide a comprehensive discussion of groundwater sustainability, including what it is, how its definition has changed over time, why traditional assessments of it are wrong, how assessments of it are ideally multidisciplinary efforts recognizing that policy is more controlling of outcomes than science, and why achieving it is difficult once pumping exceeds sustainable levels of pumping. The book will provide a nontechnical background of hydrogeology relevant to groundwater sustainability and present several case studies from around the United States and the world. The book has been designed to appeal to academics, students, and practitioners. Academics, particularly those just getting into the subject, will find the book a useful entry in terms of management concepts and political realities of attempting to achieve groundwater sustainability. It will also be useful to academics in that the book will include discussions on the history and development of groundwater sustainability and the practical aspects of aspiring to and achieving sustainable production. Although not a textbook, the book could be used as the basis for teaching a course or as a supplement to a hydrogeology or groundwater management class. Accordingly, the book will include questions and additional reading materials at the end of each chapter. This book will also be useful to practitioners through non-technical explanations of the sciences, discussions of the nuances of defining sustainability in aquifers, and the presentation of case studies where sustainable management has failed and succeeded.

Download or read book Standing between Life and Extinction written by David L. Propst and published by University of Chicago Press. This book was released on 2021-02-15 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.

Book Synopsis Groundwater Depletion in the United States (1900?2008) by : Leonard F Konikow
Download or read book Groundwater Depletion in the United States (1900?2008) written by Leonard F Konikow and published by CreateSpace. This book was released on 2014-08-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A natural consequence of groundwater withdrawals is the removal of water from subsurface storage, but the overall rates and magnitude of groundwater depletion in the United States are not well characterized. This study evaluates long- term cumulative depletion volumes in 40 separate aquifers or areas and one land use category in the United States, bringing together information from the literature and from new analy- ses. Depletion is directly calculated using calibrated ground- water models, analytical approaches, or volumetric budget analyses for multiple aquifer systems. Estimated groundwater depletion in the United States during 1900-2008 totals approx- imately 1,000 cubic kilometers (km3). Furthermore, the rate of groundwater depletion has increased markedly since about 1950, with maximum rates occurring during the most recent period (2000-2008) when the depletion rate averaged almost 25 km3 per year (compared to 9.2 km3 per year averaged over the 1900-2008 timeframe).

Book Synopsis Groundwater Flow and Thermal Modeling to Support a Preferred Conceptual Model for the Large Hydraulic Gradient North of Yucca Mountain by :
Download or read book Groundwater Flow and Thermal Modeling to Support a Preferred Conceptual Model for the Large Hydraulic Gradient North of Yucca Mountain written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to report on the results of a preliminary modeling framework to investigate the causes of the large hydraulic gradient north of Yucca Mountain. This study builds on the Saturated Zone Site-Scale Flow and Transport Model (referenced herein as the Site-scale model (Zyvoloski, 2004a), which is a three-dimensional saturated zone model of the Yucca Mountain area. Groundwater flow was simulated under natural conditions. The model framework and grid design describe the geologic layering and the calibration parameters describe the hydrogeology. The Site-scale model is calibrated to hydraulic heads, fluid temperature, and groundwater flowpaths. One area of interest in the Site-scale model represents the large hydraulic gradient north of Yucca Mountain. Nearby water levels suggest over 200 meters of hydraulic head difference in less than 1,000 meters horizontal distance. Given the geologic conceptual models defined by various hydrogeologic reports (Faunt, 2000, 2001; Zyvoloski, 2004b), no definitive explanation has been found for the cause of the large hydraulic gradient. Luckey et al. (1996) presents several possible explanations for the large hydraulic gradient as provided below: The gradient is simply the result of flow through the upper volcanic confining unit, which is nearly 300 meters thick near the large gradient. The gradient represents a semi-perched system in which flow in the upper and lower aquifers is predominantly horizontal, whereas flow in the upper confining unit would be predominantly vertical. The gradient represents a drain down a buried fault from the volcanic aquifers to the lower Carbonate Aquifer. The gradient represents a spillway in which a fault marks the effective northern limit of the lower volcanic aquifer. The large gradient results from the presence at depth of the Eleana Formation, a part of the Paleozoic upper confining unit, which overlies the lower Carbonate Aquifer in much of the Death Valley region. The Eleana Formation is absent at borehole UE-25 p#1 at Yucca Mountain, which penetrated the lower Carbonate Aquifer directly beneath the lower volcanic confining unit. The Site-scale model uses an area of very low permeability, referenced as the east-west barrier, to simulate the large hydraulic gradient. The Site-scale model is further refined in this study to provide a base-case model for exploring the geologic causes of the large hydraulic gradient.
