Dredging and the disposal of dredged material in open water often generate turbidity in the water column by suspending fine-grained particles of dredged material. Although silt curtains, or turbidity barriers, have been used extensively in an attempt to control the dispersion of this turbid water, until now there has been very little information about the actual effectiveness of silt curtains. Field and analytical studies were conducted by JBF Scientific Corporation, Wilmington, Massachusetts, as part of the DMRP to evaluate the functional capabilities and performance of silt curtains. These studies involved and evaluation of past and present silt curtain use, an analysis of silt curtain effectiveness, and the development of guidelines on silt curtain specifications, deployment methods, and limiting environmental conditions. The following discussion provides a summary of the silt curtain study.
