In a stable alluvial channel, no net erosion or deposition of sediment occurs on the average. The sediment supply rate from upstream is balanced by capacity of the flow to transport the bed material. Any successful channel design must maintain this equilibrium or establish it for channel reaches that are not stable. Design relationships between the bed material transport capacity and the hydraulic variables of flow are based primarily on data from relatively small test channels. Reliable data for equilibrium transport of bed material by flows over about twenty cfs are not adequate to insure that data from small flumes can be extrapolated to prototype designs. An investigation was conducted in the 250-ft long test channel at the USDA Sedimentation Laboratory to obtain additional data on equilibrium transport by flows up to 150 cfs. Data on the transport rates, flow friction factors, and statistical properties of the bed forms were obtained. The results are presented as basic variable correlations with the controlled variables of the experiments, depth and discharge, along with attempts to generalize the relationships by similitude principles.

A two-dimensional finite element model that simulates erosion, Transport, and deposition of suspended sediments is presented. The breadth-averaged or depth-averaged equations may be used depending on the problem to be solved. The governing equations for two phase transport are derived and then solved by the finite element method using isoparametric quadrilateral elements in which a quadratic approximation is made for the suspended sediment concentrations. Expressions used for the rates and conditions under which erosion and deposition occur are from previous experimental studies. Continuing aggregation is accounted for by specifying the settling velocity of the flocs in each element at each time step. The bed is considered to be formed of a number of layers of sediment whose physical properties change with overburden pressure. The model provides suspended sediment concentrations and bed profile at each time step. Numerical stability and convergence tests were conducted by comparing simulated results with analytic solutions and actual measurements. The original model, SEDIMENT I, was verified by comparison with measurements in a recirculating flume. The modified model, SEDIMENT II, developed for this project was verified by comparison with field measurements in the Savannah Estuary, Georgia. (Author).

Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT--OVERSTOCK SALE --Significantly reduced list price while supplies last The Erosion and Sedimentation Manual provides a comprehensive coverage of subjects in nine chapters (i.e., introduction, erosion and reservoir sedimentation, noncohesive sediment transport, cohesive sediment transport, sediment modeling for rivers and reservoirs, sustainable development and use of reservoirs, river process and restoration, dam decommissioning and sediment management, and reservoir surveys and data analysis). Each chapter is self-contained, with cross references of subjects that are discussed in different chapters of this manual. The manual also includes a list of commonly used notations used in the erosion and sedimentation literature, conversion factors between the Imperial and metric units, physical properties of water, and author and subject indexes for easy reference. Each chapter has a list of reference for readers who would like to seek out more detailed information on specific subjects. Audience The manual would be useful for researchers, university professors, graduate students, geologists, hydrographic survey analysts, municipal and state water research specialists, and engineers in solving erosion and sedimentation problems.

This book provides a broad perspective of sediment transport in rivers, reservoirs, estuaries, and coastal areas. It deals with the related fundamentals of sediment transport, computational modelling of cohesive and non-cohesive sediments transport, and sedimentation engineering management. Topics include river morphological changes after dam removal, local scour and its monitoring, marsh edge erosion, turbidity dynamics in a bay surrounded by marshes, effects of harbour construction on hydrodynamic and morphodynamic processes in a coastal area, and impact of climate change on sediment yield from a watershed, are discussed. The breath of the topics covered will be of interest to researchers and practising engineers alike. This book contains twelve chapters.

Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

Process-based morphodynamic modelling is one of the relatively new tools at the disposal of coastal scientists, engineers and managers. On paper, it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice, a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest, it should run long enough and robustly to see the real effects happen, and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next, practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally, translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell, this book provides an in-depth review of ways to model coastal processes, including many hands-on exercises.
