Abstract

A discussion of chemical modeling approaches is presented with emphasis on modeling chemicals in estuaries. An application of modeling di-n-octyl phthalate in a subestuary of Chesapeake Bay indicates that the most sensitive processes for an analyst to consider in estuary chemical modeling are dispersive transport, biological partitioning, boundary exchange, and sediment partitioning. Additional research is needed to evaluate the role of coagulation and sedimentation in such efforts. A framework for consideration of effects modeling is presented briefly.
