Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study. Discussions ondeveloping environmental tracers to fingerprint sources and amounts of groundwater at the basin scalethe critical role of vegetation in hydroecological processesnew geophysical methods in quantifying channel rechargeapplying Geographical Information System (GIS) models to land surface processescoupling process-based vadose zone to groundwater modeling, and more make this book a significant resource for hydmlogists, biogeoscientists, and geochemists concerned with water and water-related issues in arid and semiarid regions.

This interdisciplinary volume examines how nine arid or semi-arid river basins with thriving irrigated agriculture are doing now and how they may change between now and mid-century. The rivers studied are the Colorado, Euphrates-Tigris, Jucar, Limarí, Murray-Darling, Nile, Rio Grande, São Francisco, and Yellow. Engineered dams and distribution networks brought large benefits to farmers and cities, but now the water systems face multiple challenges, above all climate change, reservoir siltation, and decreased water flows. Unchecked, they will see reduced food production and endanger the economic livelihood of basin populations. The authors suggest how to respond to these challenges without loss of food production, drinking water, or environmental health. The analysis of the political, hydrological, and environmental conditions within each basin gives policymakers, engineers, and researchers interested in the water/sustainability nexus a better understanding of engineered rivers in arid lands.

This Handbook has been developed by the EPA as a resource for project managers working on addressing the environmental concerns posed by inactive mines and mineral processing sites. This is not policy or guidance, but a compendium of info. gained during many years of experience on mine site cleanup projects. Chapters: Overview of Mining and Mineral Processing Operations; Environmental Impacts from Mining; Setting Goals and Measuring Success; Community Involve. at Mining Waste Sites; Scoping Studies of Mining and Mineral Processing Impact Areas; Sampling and Analysis of Impacted Areas; Scoping and Conducting Ecological and Human Health Risk Assessments at Superfund Mind Waste Sites; Site Mgmt. Strategies; and Remediation and Cleanup Options.
