Figure 2.13. Comparison between the fluxes of 137Cs sediment to the percent flux at Sterling, Virginia for core 6. This graph demonstrated that there was a significant contribution of sediment from the watershed prior to 1972. After this time, maybe as a result of flushing due to the flooding caused by Hurricane Agnes, the sediment regime apparent changes with much less sediment now being derived from the watershed.
