Purpose: to (1) quantify the sediment input to LCE, to assess the rate of accumulation, and to predict the period of time required to accumulate given a depth of sediment; and (2) determine the max. flow velocity in the system that could be sustained without re-suspending bottom sediments and potentially exposing PCB contaminated sediment to erosion.
