DOWNLOAD EBOOKResearch on reservoir sedimentation in recent years has been aimed mainly at water resources projects in developing countries. These countries, especially in Africa, often have to cope with long droughts, flash floods and severe erosion problems. Large reservoir capacities are required to capture water provided by flash floods so as to ensure the supply of water in periods of drought. The problem arising however is that these floods, due to their tremendous stream power, carry enormous volumes of sediment which, due to the size of reservoirs, are virtually deposited in toto in the reservoir basin, leading to fast deterioration of a costly investment. Accurate forecasting of reservoir behaviour is therefore of the utmost importance. This book fills a gap in current literature by providing in one volume comprehensive coverage of techniques required to practically investigate the effects sediment deposition in reservoirs has on the viability of water resources projects. Current techniques for practically estimating sediment yield from catchments, estimating the volume of sediment expected to deposit in reservoirs, predicting sediment distribution and calculating scour downstream of reservoirs are evaluated and presented. The liberal use of diagrams and graphs to explain the various techniques enhances understanding and makes practical application simple. A major feature of the book is the application of stream power theory to explain the process of reservoir sedimentation and to develop four new methods for predicting sediment distribution in reservoirs. The book is primarily directed at practising engineers involved in the planning and design of water resources projects and at post-graduate students interested in this field of study.

DOWNLOAD EBOOKHistorically, the flow of sediment in the Missouri River has been as important as the flow of water for a variety of river functions. The sediment has helped form a dynamic network of islands, sandbars, and floodplains, and provided habitats for native species. Further downstream, sediment transported by the Missouri and Mississippi Rivers has helped build and sustain the coastal wetlands of the Mississippi River delta. The construction of dams and river bank control structures on the Missouri River and its tributaries, however, has markedly reduced the volume of sediment transported by the river. These projects have had several ecological impacts, most notably on some native fish and bird species that depended on habitats and landforms created by sediment flow. Missouri River Planning describes the historic role of sediment in the Missouri River, evaluates current habitat restoration strategies, and discusses possible sediment management alternatives. The book finds that a better understanding of the processes of sediment transport, erosion, and deposition in the Missouri River will be useful in furthering river management objectives, such as protection of endangered species and development of water quality standards.

DOWNLOAD EBOOKWritten by two of the world’s leading experts on sediment management, 'Extending the Life of Reservoirs' provides guidance on adopting sediment management practices for hydropower and water supply dam projects. It explains how ensuring long-term resilience of critical infrastructure requires early and constant attention to reservoir sedimentation processes, which can reduce the storage capacity of reservoirs and damage hydro mechanical equipment. The report provides concrete guidance on safeguarding against these effects and preserving the many important services of hydropower and dam projects, including water supply, irrigation, and renewable electricity. In particular, it stresses the importance of integrating sediment management into the early planning phases of projects. 'Extending the Life of Reservoirs' is designed to assist those evaluating dam and hydropower proposals. While for the primary audience includes policy makers, lending agencies, and general practitioners, the level of detail provided in the report should appeal to a wide array of stakeholder groups. The content is neither overly technical nor overly simplistic, and aims to provide practical and useful information. Importantly, this report provides a new perspective on the importance of sediment management that is not found in prior work. It stresses the value of sediment management measures as a robust adaptation measure to support sustainable hydropower. The techniques described in the report make sense regardless of future climate changes, but in many cases have even more value when uncertainty over future hydrological patterns is taken into account.

These water storage facilities have been created since time immemorial mainly by constructing dams accross rivers and are intended both for capturing water that would otherwise proceed down river towards the oceans or lakes as well as for storing the water for as long as possible, till when needed and used. Sediments which is naturaly released from the catchment areas into the reservoir via contributing stream is impeded by the water bodies in the reservoir which are retained by the dams and to a large extent the sediments is permanently trapped there in. This paper talks about managing the flow of reservoirs and regulated river or dam and how to improve its sustainability by balancing the needs of the society, the economy, the environment and the ecosystems.

DOWNLOAD EBOOKIn dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale.
