Abstract: A river floodplain was found to contain measurable quantities of polychlorinated biphenyls (PCBs), presumably deposited during historic flood events. A hydraulic model (HEC-2) was used to examine the relationship between the distribution of PCBs in the floodplain soils and the water surface elevation of the floods. This study demonstrated the utility of using the presence of conservation tracers in floodplain sediments as useful information in the calibration and validation of river hydraulic models.
