Book excerpt: Research 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.

Available in PDF, EPUB and Kindle. Book excerpt: Reservoir Sedimentation: Assessment and Environmental Controls appraises the issues of sedimentation in reservoirs and discusses measures that can be employed for the effective management of sediment to prolong the operational life of reservoirs. It provides information for professional consultants and policymakers to enable them to manage dams in the best possible way, in order to ensure their sustainability as well as the sustainability of water resources in general. It examines the effects of anthropogenic intervention and management of sediment in dams and reservoirs, as water resources become more sensitive and the demand for clean water continues to increase. Features: Examines the issue of sedimentation in dams and reservoirs and presents water management strategies to alleviate environmental issues Presents methods to help ensure the environmental sustainability of dams and reservoirs, as well as the sustainability of water resources- with consideration of climate change and increased demand Illustrates the spatial distribution of sedimentation characteristics for several dams using geographic information systems (GIS) Explains the relationships between loss in capacity and catchment characteristics Examines regional variation in sediment yield, defines geomorphic regions on the basis of similar hydrometeorology, physiography, geology, and vegetation affecting reservoirs

Available in PDF, EPUB and Kindle. Book excerpt: Despite the mechanisms of reservoir sedimentation being well known for a long time, sustainable and preventive measures are rarely taken into consideration in the design of new reservoirs. To avoid operational problems of powerhouses, sedimentation is often treated for existing reservoirs with measures which are efficient only for a limited time.Th

Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with one of the methods of removing sediments from reservoirs, namely the flushing of sediments through purpose built outlet works within the dam. This technique can be applied to existing dams, with adaptation of the engineering works, and to new dams. The book gives practical guidance on the necessary hydrological, hydraulic, sedimentological and topographical features for successful flushing.In this book the author draws together his wealth of experience of working in this field.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The issues surrounding the management of sediments accumulating in reservoirs remain an ongoing challenge to scientists and practitioners. All reservoirs trap inflowing sediment to some degree, leading to a suite of problems including loss of water storage capacity, impairment of navigability, loss of downstream flood-control benefits, increased flooding upstream because of streambed aggradation in the deltaic region, and sediment entrainment in hydropower equipment. The loss of storage capacity, in addition to reducing performance for water supply, hydropower and recreation, increases the pressure to develop replacement storage, especially in the face of population growth and climate change. One aspect of reservoir sedimentation that has received relatively little attention in the literature is the effect of progressive reservoir filling over time on the processes influencing sediment deposition. For example, as reservoirs become more and more filled with sediment, an increasing amount of deposition can occur above the normal-pool elevation, as a consequence of shallow overbank flows during high flow periods spreading across the alluvial surface of the sediment deposit. Much of the literature on reservoir sedimentation focuses on deposition in a reservoir with substantial remaining capacity. The evolution of the processes as the reservoir fills is of interest as well, but little attention is paid to this in the existing literature, despite possible implications for ecological succession, reservoir management, and dam removal. This dissertation employs a combination of analysis of previously collected field measurements, new field measurements using synthetic turf sediment traps, and numerical modeling to study the magnitude and spatial distribution of sediment deposition in and around Searsville Lake. I show that the alluvial surface upstream of Searsville Lake is spatially complex, and while two simple analytical models (a one-dimensional advection model and a turbulent diffusion model) have significant predictive value in determining the amount of sediment deposition, small-scale effects also play a substantial role. Additionally, simulations based on the Searsville area show results qualitatively similar to the field data in terms of the spatial complexity of erosion and deposition, as well as the relationship between hydrograph volume and magnitude of alluvial surface deposition. Sensitivity analysis shows that changes in alluvial surface roughness discretization and channel bathymetry influence erosional and depositional patterns on the alluvial surface, with varying impacts on the overall magnitude. The ordering of hydrograph events has a significant effect on the locations on the alluvial surface which experience the largest bed level change, and a moderate effect on the overall amount of sediment deposited on the alluvial surface. Finally, simulations predict deposition will preferentially occur at topographic lows, suggesting that over long times, if preferential flowpaths sample the full alluvial surface area, a relatively flat sediment surface is likely to develop. This speculation is consistent with the observed behavior at Searsville. A full modeling study of the sediment processes around Searsville--or any similar environment--featuring a full calibration and verification of the model, would further add to the understanding of the behavior of this complex environment. Long-term simulations accounting for the full range of channel processes, including migration, would be of particular interest, allowing for testing of the theory that the long term behavior of the system will be to move towards a more uniform sediment surface.

Available in PDF, EPUB and Kindle. Book excerpt: The creation of river dams and the storage of water have been a strategy for survival for many centuries. Reservoirs have diverse functions, providing irrigation, water supply, storage of water, flood control, navigation and power generation. The silting of a reservoir is an unavoidable process. Although it cannot be halted, silting can be slowed down and controlled by a variety of soil conservation practices and by modifying agricultural practices in the catchment area. Other methods of reducing silting include the placing of certain engineering structures in the river system and the introduction of adequate strategies of reservoir operation. Silting and Desilting of Reservoirs includes aspects such as hydraulics, sediment transport, silting, sediment distribution, calculation and prediction of silting and solutions to reservoir silting.
