As demand for water increases, water managers and planners will need to look widely for ways to improve water management and augment water supplies. This book concludes that artificial recharge can be one option in an integrated strategy to optimize total water resource management and that in some cases impaired-quality water can be used effectively as a source for artificial recharge of ground water aquifers. Source water quality characteristics, pretreatment and recharge technologies, transformations during transport through the soil and aquifer, public health issues, economic feasibility, and legal and institutional considerations are addressed. The book evaluates three main types of impaired quality water sourcesâ€"treated municipal wastewater, stormwater runoff, and irrigation return flowâ€"and describes which is the most consistent in terms of quality and quantity. Also included are descriptions of seven recharge projects.

This open access textbook provides a concise introduction to economic approaches and mathematical methods for the study of water allocation and distribution problems. Written in an accessible and straightforward style, it discusses and analyzes central issues in integrated water resource management, water tariffs, water markets, and transboundary water management. By illustrating the interplay between the hydrological cycle and the rules and institutions that govern today’s water allocation policies, the authors develop a modern perspective on water management. Moreover, the book presents an in-depth assessment of the political and ethical dimensions of water management and its institutional embeddedness, by discussing distribution issues and issues of the enforceability of human rights in managing water resources. Given its scope, the book will appeal to advanced undergraduate and graduate students of economics and engineering, as well as practitioners in the water sector, seeking a deeper understanding of economic approaches to the study of water management.

Because water in the United State has not been traded in markets, there is no meaningful estimate of what it would cost if it were traded. But failing to establish ground water's valueâ€"for in situ uses such as sustaining wetlands as well as for extractive uses such as agricultureâ€"will lead to continued overuse and degradation of the nation's aquifers. In Valuing Ground Water an interdisciplinary committee integrates the latest economic, legal, and physical knowledge about ground water and methods for valuing this resource, making it comprehensible to decision-makers involved in Superfund cleanup efforts, local wellhead protection programs, water allocation, and other water-related management issues. Using the concept of total economic value, this volume provides a framework for calculating the economic value of ground water and evaluating tradeoffs between competing uses of it. Included are seven case studies where ground-water valuation has been or could be used in decisionmaking. The committee examines trends in ground-water management, factors that contribute to its value, and issues surrounding ground-water allocation and legal rights to its use. The book discusses economic valuation of natural resources and reviews several valuation methods. Presenting conclusions, recommendations, and research priorities, Valuing Ground Water will be of interest to those concerned about ground-water issues: policymakers, regulators, economists, attorneys, researchers, resource managers, and environmental advocates.

Written by renowned experts in the field, this book assesses the status of groundwater models and defines models and modeling needs in the 21st century. It reviews the state of the art in model development and application in regional groundwater management, unsaturated flow/multiphase flow and transport, island modeling, biological and virus transport, and fracture flow. Both deterministic and stochastic aspects of unsaturated flow and transport are covered. The book also introduces a unique assessment of models as analysis and management tools for groundwater resources. Topics covered include model vs. data uncertainty, accuracy of the dispersion/convection equation, protocols for model testing and validation, post-audit studies, and applying models to karst aquifers.

This second edition is extensively revised throughout with expanded discussion of modeling fundamentals and coverage of advances in model calibration and uncertainty analysis that are revolutionizing the science of groundwater modeling. The text is intended for undergraduate and graduate level courses in applied groundwater modeling and as a comprehensive reference for environmental consultants and scientists/engineers in industry and governmental agencies. - Explains how to formulate a conceptual model of a groundwater system and translate it into a numerical model - Demonstrates how modeling concepts, including boundary conditions, are implemented in two groundwater flow codes-- MODFLOW (for finite differences) and FEFLOW (for finite elements) - Discusses particle tracking methods and codes for flowpath analysis and advective transport of contaminants - Summarizes parameter estimation and uncertainty analysis approaches using the code PEST to illustrate how concepts are implemented - Discusses modeling ethics and preparation of the modeling report - Includes Boxes that amplify and supplement topics covered in the text - Each chapter presents lists of common modeling errors and problem sets that illustrate concepts
