Abstract

Better procedures for mapping the distribution of contaminated sediments and their thickness in rivers, and for monitoring sediment stability, are essential for programs that must assess the need for remediation and select the procedures to be used. In this study, sediment mapping is based on an acoustic bottom-classification system, sediment thickness is measured by underwater-TV or divers, and sediment stability is monitored acoustically with a high-precision, bottom-mounted, fixed-transducer system; data are stored in a GIS. All procedures have been developed and tested at contaminated-sediment sites in the St. Lawrence River at Cornwall, Ontario, Canada.
