The progress of a mathematical simulation study concerning kepone migration in the James River Estuary between Bailey Bay and the river mouth is described. The simulation is currently underway by applying the finite element sediment and contaminant transport model, FETRA, to solve time-dependent, longitudinal and lateral distributions of sediments and kepone by taking into account sediment-kepone interaction. The FETRA code solves sediment transport for three sediment types (i.e., cohesive and noncohesive sediments, and organic materials). The model also solves kepone transport for dissolved and particulate (attached to sediments) kepone. Particulate kepone is analyzed for those adsorbed by sediment of each sediment type. The accuracy and convergence of the FETRA code were tested for simple one- and two-dimensional equations. These test results indicated excellent agreement between the computer solutions and exact analytical solutions.
