This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Texas Commission on Environmental Quality (TCEQ) uses a Water Availability Modeling System (WAM) to support long-term regional and statewide water resources planning and management. The water availability studies are based on the modeling capabilities of the Water Rights Analysis Package (WRAP). This research improves the understanding of decision support tools for short-term river basin management. Current reservoir storage levels must be considered to assess short-term frequencies and reliabilities. Conditional reliability modeling (CRM) is used to assess the likelihood of meeting targets for instream flow, reservoir storage, water supply diversion and hydroelectric power generation in the near future (next month to next several years), conditioned upon preceding storage. This study uses data for the Brazos River Basin from the TCEQ WAM System to assess key complexities of water supply reliability analysis in general and conditional reliability modeling in particular. These complexities include uncertainties associated with river basin hydrology, estimating yield-reliability relationships for individual reservoirs and multiple reservoir systems, conventional long-term planning versus short-term adaptive management and other modeling and analysis issues. The modeling capabilities of WRAP were expanded to support near real-time operation of dams under various stream flow conditions. The sensitivity to changes in modeling options is assessed for short and long-term simulations. Traditional and newly developed methodologies for estimating firm yields and water supply reliabilities are evaluated. Guidelines are developed regarding the practical application of firm yield analyses and conditional reliability modeling. Important applications of this research include real-time decision support during drought and routinely recurring operational planning activities. A case study of the drought of 2009 uses the CRM features of WRAP for these applications.

This book was released on 2004-10-14 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.

This book was released on 1983 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simply states, the purpose of the Metropolitan Washington Area Water Supply Study was to develop, analyze and recommend those alternative measures required to solve the MWA's immediate and long-term water supply problems. The findings of the study are intended as an aid to all levels of water resources managers for the evaluation of implementable, cost-effective and environmentally acceptable means to both manage the existing water supply systems and meet future water supply needs. Recognizing the study's lengthy and complex nature at the outset, the study was designed and managed as a two phased effort. The first phase addressed the immediate short-range water supply problems with the primary goal being to solve those problems through more efficient use of existing water supplies. A Progress Report was published in August 1979 which presented the evaluation of the short-range problems and solutions to the MWA's water supply problems. Since 1979 the study has concentrated on the second phase of the investigation dealing with potential long-range water supply problems. The goal of the study's second phase was to determine the feasibility of providing additional sources of raw water in order to meet long-range term needs.

Available in PDF, EPUB and Kindle. Book excerpt: Many challenges, including climate change, face the Nation¿s water managers. The Intergovernmental Panel on Climate Change (IPCC) has provided estimates of how climate may change, but more understanding of the processes driving the changes, the sequences of the changes, and the manifestation of these global changes at different scales could be beneficial. Since the changes will likely affect fundamental drivers of the hydrological cycle, climate change may have a large impact on water resources and water resources managers. The purpose of this interagency report is to explore strategies to improve water management by tracking, anticipating, and responding to climate change. Charts and tables.

Download or read book River Reservoir System Water Availability Modeling Support for Drought Management written by Ankit Bista and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Availability Modeling (WAM) System maintained by the Texas Commission on Environmental Quality (TCEQ) consists of the Water Rights Analysis Package (WRAP) and datasets for all the river basins of Texas. The modeling system is used to support long-term regional and statewide planning and evaluation of water right permit applications. The research is designed to explore and improve WRAP/WAM capabilities as a decision-support tool for drought management. The WRAP/WAM model for the Colorado River Basin is applied in this research in both long-term planning and short-term conditional reliability modeling (CRM) modes. A strategy using iterative long-term simulations is developed for modeling water management plans that combine interruptible and firm water supply commitments. The methodology is tested and demonstrated by application to the LCRA System. Improvements in water supply reliabilities provided by off-channel storage are also investigated in the simulation study. The research is designed to explore and improve modeling capabilities in general, not to support specific decisions regarding water management in this particular river basin. CRM features in WRAP provide short-term storage frequency and supply reliability analyses conditioned on preceding reservoir storage and can be employed as a decision-support tool for water management during drought or operational planning studies for preparing for future drought. The research explores alternative methods and combinations of options for performing various CRM tasks and develops several additional new options. Climate teleconnection patterns, drought indices, and flow persistence are investigated from the perspective of potential improvements to WRAP/WAM CRM capabilities. The literature regarding climate cycles and metrics for identifying these cycles is reviewed. Correlation analyses are performed to analyze the relationship between flows at selected sites on the Colorado River and various climate cycle indices. The correlations are generally found to be fairly weak. The Rapid Intervention Program (RIP) is designed for improving on-farm irrigation management strategies. A new interactive web interface tool being developed by other researchers at Texas A&M University, called the Irrigation Water-Use Efficiency Maximizer (IWEM), will link WRAP with RIP. WRAP CRM methods are tested and compared to determine the optimal combination of options for use with the IWEM platform.
