This Coastal and Hydraulics Engineering Technical Note (CHETN) contains a literature review giving a brief compilation of case studies related to potential methods adopted for reducing sediment deposition in harbors and navigation channels. All over the world there are numerous sites where the bed consists of noncohesive sediment (sand and silt) alone. Examples of important engineering projects in areas consisting of clays alone are probably very few. Invariably, fine sediments occurring in the natural environment consist of a mixture of cohesive and noncohesive sediments. The literature review included in this technical note covers both types of sediments. In addition to gathering information on projects executed at various sites, this literature review also includes findings of hydraulic and numerical model investigations. These include results of investigations on the effect of construction of new structures, modification of existing structures, or modification of site conditions. Experience gained through these case studies will offer valuable guidance in planning and designing future projects. Note that those options that were investigated in laboratories for research purposes but did not work when adopted for a particular project are included because they might work at other locations.
