Abstract: Particulate and dissolved pollutant transport rates are predicted using a pollutant transport modeling system. The latter is a finite element model capable of simulating two-dimensional (depth-averaged) transport and interaction of cohesive sediments and hydrophilic pollutants in rivers and estuaries. This modeling system includes a hydrodynamic module, water quality module, cohesive sediment transport module, and both dissolved and particulate pollutant transport modules. The modeling system was used to simulate a laboratory scale pollutant transport experiment. Reasonable agreement between predicted and measured pollutant concentrations was achieved.
