Erosion & sedimentation in alluvial river is a continuous phenomenon in nature. This paper focuses the major governing mechanisms and influencing factors. River morphology, silt component and river meandering affect in shaping river cross section. The amount of sediment and erosion in a river can be predicted by the available computer models for the efficient planning of hydraulics structures. Control of adverse effect of this process in a river channel to make it more smooth, stable and efficient for all purpose are also discussed in this paper. [Author's abstract].

This text offers a thorough analysis of erosion, transport and sedimentation of soil and solid particles by surface waters. The author has aimed for simplicity of presentation, stressing physical understanding based on Newtonian mechanics. He explains fundamental concepts pertaining to the hydrodynamic forces exerted on solid particles, with a lucid treatment of potential flow, viscous flow, turbulent flow, and boundary layers. The text presents detailed methods and procedures commonly used in engineering practice. It also features a variety of exercises and problems for students and researchers, along with numerous examples and case studies for practicing engineers seeking solutions to real-world problems. Students, reseachers, and practitioners in civil, environmental, agricultural, mechanical and chemical engineering, hydrology, sedimentology, and natural resources will find valuable information in this text intended for the classroom and beyond.

Download Sediment Control in Alluvial Rivers Using Simulation-based Optimization Book in PDF, ePub and Kindle
During storm events in rivers and watersheds, the peak runoff may creates excess erosion and deposition in channels or river reaches and cause changes in flow characteristics and fluvial geomorphology. Severe sediment erosion such as in-stream sever bed and bank erosion or gullying can threaten the stability of in-stream hydraulic structures, river banks, levees, and underground utilities. On the other hand, large amounts of sediment deposition can significantly reduce the flow capacity of channel or reservoir and increases further possibility of flooding. Therefore, sediment control is generally required for rivers and watersheds conservation purposes to maintain stable flow systems in channels and river reaches. This study proposes an innovative optimization procedure to control sediment in alluvial rivers during extreme events based on the integration of sediment transport model with optimization approach. The aim of this study is to develop a decision making method which to minimize morphological changes in alluvial networks due to extreme events (e.g. floods and dam removals) under operational constraints so that the optimal sediment control can be achieved. The developed model combines an optimization module with a well-established one-dimensional model (CCHE1D) for simulating open channel flows and sediment transport in alluvial rivers. An adjoint sensitivity model for CCHE1D and an optimization algorithm are developed to search for the best solution of the optimal control action. The developed model will be applied to control morphological changes by diverting both sediment and water during flood or dam removal. It is believed that the developed tool will facilitate planning and management of sediment control.

Download Modeling and Practice of Erosion and Sediment Transport under Change Book in PDF, ePub and Kindle
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.

Download Reservoir Sedimentation Book in PDF, ePub and Kindle
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.
