Available in PDF, EPUB and Kindle. Book excerpt: "This book provides an excellent overview of contemporary problems in reservoir management, from planning aspects of large multi-objective reservoirs and regarding small farm dams in Africa, to governmental matters, to sedimentation issues, to climate change impacts. Given the stochastic nature of hydrological conditions, the limited information available to characterize it and the multi-faceted targets of reservoir management, reservoir planning and operation are ambitious challenges for hydrologists and water managers. Reservoir management considers supply and demand. Demand includes the objectives of water management, but also the expectations of society, which develop with time; ecological targets for reservoir operation are now more important, social aspects and requirements are relevant and there are new constraints and objectives for operation of even older dams. The supply side has become more uncertain with increasing awareness of climate change causing growing concern about its impacts on the performance and reliability of existing and planned water management systems."--Provided by publisher.

The contributors encompass forecasts over a wide range of temporal scales, from weather over the next few hours to the climate months or seasons ahead, and address the impact of these forecasts on human behaviour. Economic Value of Weather and Climate Forecasts seeks to determine the economic benefits of existing weather forecasting systems and the incremental benefits of improving these systems, and will be an interesting and essential reference for economists, statisticians, and meteorologists.
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
Download or read book Introduction to Hydrometeorology written by J. P. Bruce and published by Elsevier. This book was released on 2013-10-22 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Hydrometeorology is the study of the hydrolic cycle, which is the circulation of water from the seas, into the atmosphere, and back to either land or sea. This book describes hydrometeorology or the application of meteorology to problems that pertain to hydrology, and then discusses the approach, through meteorology, to the solution of hydrologic problems. This text outlines observation methods on the subject and discusses the applications of hydrometeorology to problems encountered in the study of river and lake behaviors. Topics include precipitation, melting of ice, streamflows, lakes, evaporation, and evapotranspiration. The frequently used methods in analysis, such as employing statistics to hydrometereological problems, precipitation analysis, and streamflow routing are explained. This text also shows how extending streamflow records can be helpful in predicting the regime or course of a stream in the future. Records of seasonal and annual flow, flood runoff, peak discharge, as well as seasons of low flow and drought become useful tools in estimating the frequency and magnitude of streamflows. After which, the book discusses possible engineering designs in irrigation, storm sewers, and reservoirs. The text looks into the ways how human has influenced the hydrologic cycle through induced precipitation, melting of ice covers, and urbanization. Lastly, some climactic trends and cycles that bring about climate change and water resource development are discussed. This text can be used by students studying hydrology and those with meteorology majors. This book can also be read by meteorologists, environmentalists, and people working in general earth sciences.
Download or read book Improving Multi reservoir Water Supply System Operation Using Ensemble Forecasting and Global Sensitivity Analysis written by Reza Limon and published by . This book was released on 2019 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to improve the cost-effectiveness, reliability and resilience of water supply system operation through the utilization of ensemble forecasting and optimization of the operating policies. For the effective operation of a multi-reservoir water supply system skillful inflow and outflow forecasts are required. To that end, this research first assesses the value of medium-range ensemble precipitation forecasts generated with the HEFS developed by the US NWS in increasing skill and lead time of ensemble inflow forecasts. The skill of reservoir outflow forecasts is then assessed using three different models with varying complexity. Also assessed in the above is the relative importance of meteorological, hydrologic and reservoir modeling uncertainty in outflow forecasts. Lastly, the proposed policy modifications were optimized via global sensitivity analysis using the variance-based Sobol method to improve cost-effectiveness of the system operation further. The analysis results identify influential policies, assess their impact on the cost response of the system operation, and determine policy modifications. Main conclusions of this research follow below. Compared to using only the 72-hr RFC QPF, the use of the medium-range precipitation forecasts from GEFS increases skill and lead time of mean daily inflow forecasts from HEFS by up to 3 days for significant events. The HEFS-produced multi-daily inflow forecasts are significantly more skillful than the daily inflow forecasts, and extends the lead time of skillful forecasting further. It is demonstrated that the use of the HEFS-produced ensemble inflow forecasts results in significant savings in mean annual pumping cost, compared to the TRWD's current practice of inflow forecasting. Among the three reservoir models considered in this work, RiverWare provides the largest skill in MEFP-GEFS-forced outflow forecasts. It is shown that meteorological, hydrologic and reservoir modeling uncertainties are comparably importance in improving skill of reservoir outflow forecasts. However, the decomposition of total predictive uncertainty into the above three indicates that the relative importance varies significantly with lead time and among different reservoir models. Evaluation of reservoir outflow forecasts for specific large outflow events shows that, although the reservoir outflow forecasts forced by the HEFS inflow forecasts are not probabilistically unbiased for very large to extreme events, the ensemble spread of the outflow forecasts is generally able to encompass the observed pool elevation and outflow. As such, the HEFS inflow forecasts provide additional critical information not available from single-valued forecasts for risk-based decision making in reservoir operations.Among the five operating policies selected for considered for modification, only one or two exert large influence on the cost for a given year. The influential polices, however, vary very significantly from year to year. The cost response of the system to policy modifications is complex and shows large interannual variations. Hydroclimatic conditions, storage states, inflow, and demand largely determine the influential policies and their modifications. It is shown that annually-varying, or dynamic, determination of policy modifications offer significantly larger potential for cost savings than using optimized, but fixed, policy modifications.
