ABSTRACT

Sediment settling, deposition, and resuspension are sediment-water exchange processes that play an important role in determining contaminant exposures at contaminated sites, under both uncontrolled conditions and following remediation. Because of its importance in the long-term fate of contaminants, considerable research has been conducted in this area. The goal of this chapter is to provide a review of the knowledge base and approaches for quantifying the processes governing the transport of particles and chemicals adsorbed to those particles across the sediment-water interface. The review is not exhaustive, but rather represents the opinions and experiences of the authors aimed at providing the reader with both theoretical and quantitative information on this topic.
