Long-term, multidimensional water quality modeling, using directly linked hydrodynamic and water quality models, can become prohibitively expensive. In this report, fine scale, short time-step hydrodynamic model output is linked with coarse grid, longer time-step multiple-box water quality model. The formulation, limitations, and adaption for use in applications of the Water Quality Analysis Simulation Program WASP, the US Environmental Protection Agency multiple-box model, are discussed. Linkage of the multiple-box model to two hydrodynamic models is explained. Dye tracer simulations are used to compare mass transport by the box model with mass transport by the directly linked models for three applications Savannah River Estuary, Mississippi Sound, and DeGray Lake.
