Available in PDF, EPUB and Kindle. Book excerpt: Reservoir systems are subject to several uncertainties that are the result of imperfect knowledge about system behavior and inputs. A major source of uncertainty arises from the inability to predict future inflows. Fortunately, it is often possible to generate probabilistic forecasts of inflow volumes in the form of probability density functions or ensembles. These inflow forecasts can be coupled with stochastic management models to determine reservoir release policies and provide stakeholders with meaningful information of upcoming system responses such as reservoir levels, releases, flood damage risks, hydropower production, water supply withdrawals, water quality conditions, navigation opportunities, and environmental flows, among others. This information on anticipated system responses is also expressed in the form of forecasts that must reliably represent the actual system behavior when it eventually occurs. The first part of this study presents an assessment methodology that can be used to determine the consistency of ensemble forecasts through the use of relative frequency histograms and minimum spanning trees (MST). This methodology is then used to assess a management model's ability to produce reliable ensemble forecasts. It was found that neglecting to account for hydrologic state variables and improperly modeling the finite management horizon decrease ensemble consistency. Several extensions to the existing management model are also developed and evaluated. The second portion of this study involves the management of the uncertainties in reservoir systems. Traditional management models only find management policies that optimize the expected values of system benefits or costs, thereby not allowing operators and stakeholders to explicitly explore issues related to uncertainty and risk management. A technique that can be used to derive management policies that produce desired probabilistic distributions of reservoir system outputs reflecting stakeholder preferences is developed. This technique can be embedded in a user-interactive framework that can be employed to evaluate the trade-offs and build consensus in multi-objective and multi-stakeholder systems. The methods developed in this dissertation are illustrated in case studies of real reservoir systems, including a seven-reservoir, multi-objective system in California's Central Valley.

This book was released on 2020-12-23 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past five decades, we have witnessed a tremendous evolution in water resource system management. Three characteristics of this evolution are of particular note: First, the application of the systems approach to complex water management problems has been established as one of the most important advances in the field of water resource management. Second, the past five decades have brought a remarkable transformation of attitude in the water resource management community towards environmental concerns and action to address these concerns. Third, applying the principles of sustainability to water resource decision-making requires major changes in the objectives on which decisions are based, and an understanding of the complicated inter-relationships between existing ecological, economic, and social factors. The Special Issue includes 15 contributions that offer insights into contemporary problems, approaches, and issues related to the management of complex water resources systems. It will be presumptuous to say that these 15 contributions characterize the success or failure of the systems approach to support water resources decision-making. However, these contributions offer interesting lessons from current experiences and highlight possible future work.

This book was released on 2002-06-07 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the ideal world, major decisions would be made based on complete and reliable information available to the decision maker. We live in a world of uncertainties, and decisions must be made from information which may be incomplete and may contain uncertainty. The key mathematical question addressed in this volume is "how to make decision in the presence of quantifiable uncertainty." The volume contains articles on model problems of decision making process in the energy and power industry when the available information is noisy and/or incomplete. The major tools used in studying these problems are mathematical modeling and optimization techniques; especially stochastic optimization. These articles are meant to provide an insight into this rapidly developing field, which lies in the intersection of applied statistics, probability, operations research, and economic theory. It is hoped that the present volume will provide entry to newcomers into the field, and stimulation for further research.

Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is a vital resource of water, in some regions of the world the only source of fresh water. Its use for domestic use and agriculture dates back thousands of years. In recent decades the over-exploitation and unabated use of this resource has lead to severe environmental problems such as resource depletion, land subsidence and groundwater contamination. To mitigate these adverse impacts and protect this valuable resource, it is imperative that rational groundwater management practices and policies as well as robust modeling and analysis tools be developed. This volume and the accompanying USB memory card include the abstracts and full papers that were presented at the 6th International Groundwater Symposium that was held in Kuwait between 19 and 21 of November, 2012. The Symposium was jointly organized by the Kuwait Institute for Scientific Research and the Groundwater Hydraulics and Management Committee of the International Association for Hydro-Environment Engineering and Research (IAHR). More than 100 researchers, engineers, geologists and water specialists from more than 20 countries attended the Symposium to exchange ideas and expertise relating to the latest developments in the fi eld. The papers presented at the Symposium were organized under the following themes: modeling and management under uncertainty, sustainable groundwater management in arid and semiarid environments, Aquifer Storage and Recovery (ASR) as a groundwater management tool, management solutions for groundwater rise problems, fl ow and transport modeling, and subsurface contamination and remediation. This volume provides a state-of-the-art discussion of the latest issues relating to groundwater exploration, management and protection, with an emphasis on bridging the gap between research practice and policy. The volume will serve as an important reference to students, researchers, modelers as well as practitioners and policy makers.
