Sedimentation engineering embraces the identification, planning, analysis, and remediation, principally in the context of civil and hydraulic engineering practice, of projects or technical investigations to avoid and/or mitigate problems caused by sedimentation processes. These processes include erosion, entrainment, transport, deposition, and compaction of sediment. External agents and forces driving these processes may include water, wind, gravity, and ice. Human activities also affect sedimentation processes. This volume of Sedimentation Engineering, referred to herein as Manual 0, focuses primarily on physical processes, measurements, modeling, and the practice of sedimentation engineering, mainly in the context of rivers and inland water bodies. (Chapter 4, however, addresses fine sediments topics, including those found in coastal and estuarine environments.) The original ASCE Manual 54 Sedimentation Engineering, edited by Vito A. Vanoni ( 975), represents a 0-year effort by the Task Committee for the Preparation of a Manual on Sedimentation under the coordination of the Sedimentation Committee of the Hydraulics Division of ASCE. Professor Vanoni and the Task Committee assembled and organized state-of-the-art information on sediment mechanics and sedimentation engineering available at the time. Since then, awareness of the importance, scope, and potential consequences of sedimentation processes in relation to civil engineering works, human activities, and the environment has greatly increased. Also greatly expanded are the scientific and engineering understanding and knowledge of underlying processes related to sedimentation engineering. Manual 0 is designed to update selected topics in the original manual and to present recent advances and new topics in sedimentation engineering as a complement to the chapter 1 |
