AB: Nutrient transport in the Chester River, a tributary to the Chesapeake Bay, was studied through modeling. A eutrophication model, CE-QUAL-ICM, was linked to a three-dimensional hydrodynamic model, CH3D-Z, and a watershed model, HSPF. The model consists of nutrient kinetics in the water column and diagenesis in the sediments. The model was calibrated with three-year long term survey data in the Bay and verified with one-year intensive survey data in the Chester River. The benthic flux was also calibrated using multiyear survey data. The control of lower portion of the River by the dynamics of the adjacent Bay water was apparent. Sensitivity study shows only the local effect of both waste load and distributed load from the surrounding watershed basins to the River, confined to the upper and middle portion of the River.
