Book Synopsis Delta Waters by : National Research Council
Download or read book Delta Waters written by National Research Council. This book was released on 2013-12-12. Available in PDF, EPUB and Kindle. Book excerpt: The Water Institute of the Gulf is a not-for-profit, independent research institute dedicated to advancing the understanding of coastal, deltaic, river and water resource systems, both within the Gulf Coast and around the world. Their mission supports the practical application of innovative science and engineering, providing solutions that benefit society. Those who make policy for coastal and deltaic systems, as well as managers of natural resources, need high-quality science and engineering to guide their decisions. The Water Institute of the Gulf began operations in 2012 to address exactly this sort of challenge. Delta Waters offers advice to The Water Institute of the Gulf that it might use as part of its strategic planning process. This report focuses on strategic research to support integrated water resources management in the lower Mississippi River delta and includes international comparative assessments. The recommendations of Delta Waters promote a human and environmental systems approach to scientific research that supports integrated water and environmental resources management in the lower Mississippi River and delta, and offers ideas regarding comparative assessments with other, relevant deltaic regions around the world. This report provides input for research into common deltaic problems and challenges, identifies strategic research for The Water Institute of the Gulf, and suggests ways that the organization can utilize knowledge gained from the lower Mississippi River and delta system in developing a research program to support water management decisions in other large river/delta complexes.

Book Synopsis Flowback and Produced Waters by : National Academies of Sciences, Engineering, and Medicine
Download or read book Flowback and Produced Waters written by National Academies of Sciences, Engineering, and Medicine. This book was released on 2017-02-27. Available in PDF, EPUB and Kindle. Book excerpt: Produced waterâ€"water from underground formations that is brought to the surface during oil and gas productionâ€"is the greatest volume byproduct associated with oil and gas production. It is managed by some combination of underground injection, treatment and subsequent use, treatment and discharge, or evaporation, subject to compliance with state and federal regulations. Management of these waters is challenging not only for industry and regulators, but also for landowners and the public because of differences in the quality and quantity of produced water, varying infrastructure needs, costs, and environmental considerations associated with produced water disposal, storage, and transport. Unconventional oil and gas development involves technologies that combine horizontal drilling with the practice of hydraulic fracturing. Hydraulic fracturing is a controlled, high-pressure injection of fluid and proppant into a well to generate fractures in the rock formation containing the oil or gas. After the hydraulic fracture procedure is completed, the injected fluid is allowed to flow back into the well, leaving the proppant in the newly created fractures. As a result, a portion of the injected water returns to the surface and this water is called "flowback water" which initially may mix with the naturally occurring produced water from the formation. The chemistry and volume of water returning to the surface from unconventional oil and gas operations thus changes during the lifetime of the well due to the amount of fluid used in the initial stage of well development, the amount of water naturally occurring in the geologic formation, the original water and rock chemistry, the type of hydrocarbon being produced, and the way in which production is conducted. The volume and composition of flowback and produced waters vary with geography, time, and site-specific factors. A workshop was conducted by the National Academies of Sciences, Engineering, and Medicine to highlight the challenges and opportunities associated in managing produced water from unconventional hydrocarbon development, and particularly in the area of potential beneficial uses for these waters. This publication summarizes the presentations and discussions from the workshop.

Book Synopsis River Science at the U.S. Geological Survey by : National Research Council
Download or read book River Science at the U.S. Geological Survey written by National Research Council. This book was released on 2007-05-24. 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.

Book Synopsis Challenges and Opportunities in the Hydrologic Sciences by : National Research Council
Download or read book Challenges and Opportunities in the Hydrologic Sciences written by National Research Council. This book was released on 2012-11-02. Available in PDF, EPUB and Kindle. Book excerpt: New research opportunities to advance hydrologic sciences promise a better understanding of the role of water in the Earth system that could help improve human welfare and the health of the environment. Reaching this understanding will require both exploratory research to better understand how the natural environment functions, and problem-driven research, to meet needs such as flood protection, supply of drinking water, irrigation, and water pollution. Collaboration among hydrologists, engineers, and scientists in other disciplines will be central to meeting the interdisciplinary research challenges outline in this report. New technological capabilities in remote sensing, chemical analysis, computation, and hydrologic modeling will help scientists leverage new research opportunities.
