Abstract
The present invention uses one or more sediment survey techniques to map the sediment of a water course in three dimensions. The sediment survey techniques result in sediment definition that may be used to identify zones of sediment (whether areas or volumes) that are likely to contain contaminants. This may be based on the identity of the sediment, the location of the sediment in the water course, the depth of the sediment and/or the thickness of the sediment layer. In one embodiment, the sediment survey techniques, and the resulting sediment definition, may be used in combination with geomorphology techniques to calculate an adjusted contaminant concentration for sediment zones. Based on the adjusted contaminant concentrations for a site, selective sediment removal may be used to achieve the most effective removal of contaminant with the least of sediment removal or sediment testing.
