Abstract: Mathematical models are useful tools for assessing effects of chemical,biological,and phys-ical transformation processes on chemicals that are discharged into the aquatic environment.Many mathematical models have been developed for simulating transport and fate of toxicchemicals in rivers and lakes [Schnoor 1984,Thomann and DiToro 1983,Ambrose et al.1983,1988,McCorquodale et al.1986,Halfon and Brueggemann 1990,Dickson et al.1982,Onishiand Wise 1979,Baker 1980].Most of these models are either one dimensional or simple box-type models,in which the stream or lake is considered as a series of interconnected well-mixedvolume segments.In this paper,a two-dimensional computer model is developed for chemicalspills in rivers.The model is applied to the upper St.Lawrence River,which is the majornavigation corridor for commodities passing thorough the Great Lakes -St.Lawrence Seawaynavigation system.There has been much concern over the possibility of accidental spills ofhazardous chemicals in the upper St.Lawrence River.A computer simulation model that canbe used to assist the containment and cleanup effort in the events of such a spill is needed.Besides assisting remedial actions,such a model can also be used to study the impact of thespill on the river water quality.
