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.

The Eastern Nile riparian countries Egypt, Ethiopia and Sudan are currently developing several reservoir projects to contribute to the needs for energy and food production in the region. The Nile Basin, particularly the Eastern Nile Sub-basin, is considered one of a few international river systems with potential conflicts between riparian countries. In the absence of formal mechanisms for collaboration, the transboundary nature of this basin makes sound water resources development challenging. The large seasonal and inter-annual variability of the river flow exacerbates those challenges. A further complication is the high sediment load in the Eastern Nile rivers during the high flow season. This study contributes to fill relevant knowledge gaps through a better understanding of the methods needed for a complex system of multipurpose reservoirs, considering both water quantity and sediment load. The study quantifies the impacts of water resources development in the Eastern Nile basin and identifies system management options at both regional and country level. Developing a collaborative and unified perspective of the countries towards new projects can be beneficial for all. New operation rules are proposed for improving operation of the current system when new infrastructures are developed and operated either unilaterally or, ideally, cooperatively.

Siltation in reservoirs has become an important problem when dams are getting older and stop functioning when the sediment has accumulated to a certain extent. With proper sediment management techniques, negative effects of sediment can be avoided and reservoir life and performance can be improved.This volume deals with reservoir sedimentation, dep

This book introduces methods for solving the technical and economic problems posed by water reservoirs, so as to ensure they have the best possible economic and social effect. The significance of reservoirs and the development of their function in water management is assessed, and they are classified according to origin and placing. Among the methods for solving the reservoir's function, both graphical and numerical procedures are described, based on the probability theory and mathematical statistics. In the explanation of the supply function of the reservoirs, attention is paid to the processing of hydrological data, the respective probability distribution is assessed, the theory of stochastic processes is explained, and methods of modelling the sequence of mean annual and monthly discharges are mentioned. The demands of consumers and the reliability of water supply are analysed. All types of reservoir discharge control are presented, i.e. multi-year, annual, short-term and compensation. A solution is given for the discharge control in reservoir systems and in special cases of water management, as well as in individual reservoirs. To describe the flood control function of reservoirs, hydrological data are evaluated, the precision of the flood regime characteristics is assessed, the flood routing in a reservoir is resolved, and the question of flood control is discussed. Control of a reservoir is ensured by a special space, as well as by utilizing the supply and overflow components of the reservoir. A separate part is devoted to the water management operations of reservoirs, mentioning the rules for control of the discharge from reservoirs in permanent operation, mainly using central control, and for the study and evaluation of the water management function of reservoirs. The last part of the book describes solutions for new reservoir functions resulting from their incorporation into water management systems and their function in the environment. The basic types of water management systems are described, as well as conditions for their optimal operation. In a similar way, the distribution of investment and operation costs for the various parts of a complex water management project are discussed in detail, as well as the economic impact of the reliability of water supply and flood control. The physical, chemical, biological and social consequences of reservoirs and their significance in creating a cultural landscape are analysed. The book is mainly intended for those who are involved in the development, preparation and operation of water management schemes and students of graduate and post-graduate courses in the field of water management.
