Abstract: Long term, multi-dimensional water quality modeling in estuaries and coastal embayments using a directly linked hydrodynamic and water quality model can be prohibitively expensive. In this paper, fine scale, short time step hydrodynamic model output was linked with a coarse grid, longer time step finite segment type water quality model. Dye tracer simulations were used to compare mass transport by the finite segment model relative to mass transport by models directly linked to the hydrodynamic simulation. Refs.
