MANAGING CONTAMINATED SEDIMENTS USING A HYDRODYNAMIC MODEL AND A GIS

A method for managing contaminated sediments when reviewing remediatio n options is proposed. The method uses a Geographic Information System (GIS) to provide depth data for a hydrodynamic model which simulates the current distribution within the body of water under various flood events. Information on sediment size is utilized in conjunction with t he current magnitudes to determine if sediments are being transported away from the immediate vicinity of the source and into the surroundin g water body. This method is successfully applied to the Crary Park Ma rina section of the Otonabee River near Peterborough, Ontario.
