This book was released on 2018-11-30 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solving problems related to use of water resources will be of paramount importance in coming decades as increasing pressure from growing populations, climate change, extreme weather, and aging water-related infrastructure threaten water availability and quality. The Water Mission Area (WMA) of the U.S. Geological Survey (USGS) has a long-established reputation for collecting and delivering high-quality, unbiased scientific information related to the nation's water resources. WMA observations help inform decisions ranging from rapid responses during emergencies such as hurricanes, floods, and forest fires, to the long-term management of water resources. Produced at the request of USGS, this report identifies the nation's highest-priority water science and resources challenges over the next 25 years. Future Water Priorities for the Nation summarizes WMA's current water science and research portfolio, and recommends strategic opportunities for WMA to more effectively address the most pressing challenges.

This book was released on 2002-03-05 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Geological Survey (USGS) established the National Water Quality Assesment (NAWQA) program in 1985 to assess water quality conditions and trends in representative river basins and aquifers across the United States. With this report, the NRC's Water Science and Technology Board has provided advice to USGS regarding NAWQA five separate times as the program evolved from an unfunded concept to a mature and nationally-recognized program in 2002. This report assesses the program's development and representative accomplishments to date and makes recommendations on opportunities to improve NAWQA as it begins its second decade of nationwide monitoring.

Download or read book Toward a Sustainable and Secure Water Future written by National Research Council and published by National Academies Press. This book was released on 2009-09-03 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is our most fundamental natural resource, a resource that is limited. Challenges to our nation's water resources continue to grow, driven by population growth, ecological needs, climate change, and other pressures. The nation needs more and improved water science and information to meet these challenges. Toward a Sustainable and Secure Water Future reviews the United States Geological Survey's (USGS) Water Resource Discipline (WRD), one of the nation's foremost water science organizations. This book provides constructive advice to help the WRD meet the nation's water needs over the coming decades. Of interest primarily to the leadership of the USGS WRD, many findings and recommendations also target the USGS leadership and the Department of Interior (DOI), because their support is necessary for the WRD to respond to the water needs of the nation.

Download or read book River Science at the U S Geological Survey written by National Research Council and published by National Academies Press. This book was released on 2007-05-24 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers provide about 60 percent of the nation's drinking water and irrigation water and 10 percent of the nation's electric power needs. The multiple and sometimes incompatible services demanded of rivers often lead to policy and management conflicts that require the integration of science-based information. This report advises the U.S. Geological Survey on how it can best address river science challenges by effectively using its resources and coordinating its activities with other agencies. The report identifies the highest priority river science issues for the USGS, including environmental flows and river restoration, sediment transport and geomorphology, and groundwater surface-water interactions. It also recommends two cross-cutting science activities including surveying and mapping the nation's river systems according to key physical and landscape features, and expanding work on predictive models, especially those that simulate interactions between physical-biological processes. The report identifies key variables to be monitored and data-managed. It proposes enhancements in streamflow, biological, and sediment monitoring; these include establishing multidisciplinary, integrated reach-scale monitoring sites and developing a comprehensive national sediment monitoring program. Finally, it encourages the USGS to be at the forefront of new technology application, including airborne lidar and embedded, networked, wireless sensors.

Download or read book Groundwater Surface Water Interactions written by Habil. Jörg Lewandowski and published by MDPI. This book was released on 2020-12-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a paradigm shift in our understanding of groundwater–surface water interactions: surface water and aquifers were long considered discrete, separate entities; they are now understood as integral components of a surface–subsurface continuum. This book provides an overview of current research advances and innovative approaches in groundwater–surface water interactions. The 20 research articles and 1 communication cover a wide range of thematic scopes, scales, and experimental and modelling methods across different disciplines (hydrology, aquatic ecology, biogeochemistry, and environmental pollution). The book identifies current knowledge gaps and reveals the challenges in establishing standardized measurement, observation, and assessment approaches. It includes current hot topcis with environmental and societal relevance such as eutrophication, retention of legacy, and emerging pollutants (e.g., pharmaceuticals and microplastics), urban water interfaces, and climate change impacts. The book demonstrates the relevance of processes at groundwater–surface water interfaces for (1) regional water balances and (2) quality and quantity of drinking water resources. As such, this book represents the long-awaited transfer of the above-mentioned paradigm shift in understanding of groundwater–surface water interactions from science to practice.

Download or read book Documentation of the Surface Water Routing SWR1 Process for Modeling Surface Water Flow with the U S Geological Survey Modular Groundwater Model MODFLOW 2005 written by Joseph Hughes and published by CreateSpace. This book was released on 2014-04-16 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new Surface-Water Routing (SWR1) Process was written for use with the U.S. Geological Survey (USGS) MODFLOW-2005 groundwater model. The SWR1 Process is designed to simulate surface-water routing in one- and two-dimensional surface-water features and surface-water/groundwater interactions. The performance of this computer program has been tested in models of hypothetical surface-water systems and integrated surface-water/groundwater systems; however, future applications of the programs may reveal errors that were not detected in the test simulations. Users are requested to notify the USGS if errors are found in the documentation report or in the computer program.
