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).

Prepared for the 2013 National Climate Assessment and a landmark study in terms of its breadth and depth of coverage, this report blends the contributions of 120 experts in climate science, economics, ecology, engineering, geography, hydrology, planning, resources management, and other disciplines to provide the most comprehensive, and understandable, analysis to date about climate and its effects on the people and landscapes of Arizona, California, Colorado, Nevada, New Mexico, and Utahβ€”including the U.S.-Mexico border region and the lands of Native Nations.What is the climate of the Southwest like today? What has it been like in the past, and how is it projected to change over the 21st century? How will that affect water resources, ecosystems, agricultural production, energy supply and delivery, transportation, human health, and a host of other areas? How vulnerable is the region to climate change? What else do we need to know about it, and how can we limit its adverse effects?In addressing these and other questions, the book offers decision makers and stakeholders a substantial basis from which to make informed choices that will affect the well-being of the region’s inhabitants in the decades to come.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors?most with decades of experience?review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining water; impacts from exotic species; unintended consequences of biological control; the role of small mammals; watershed response to beavers; watershed and riparian changes; changes below large dams; water birds of the Colorado River Delta; and terrestrial vertebrates of mesquite bosques.
