A MICROCOMPUTER MODEL OF CONTAMINANT TRANSPORT IN AN AQUATIC SYSTEM

A micro computer model was developed for routing chemical waste contam ination through a small aquatic system. The capabilities of this simul ation model include the following characteristics: a) It distributes c ontamination by advection and dispersion along the longitudinal axis o f the system. b) It may be discretized into any number of segments (ve rtical planes normal to the longitudinal axis) as may be appropriate t o describe spatial variations in chemical contamination, c) It is capa ble of treating instantaneous, continuous, or time varying releases of chemical waste contamination. d) It provides for temporal description of contamination throughout the system. e) It provides for adsorption and desorption by both vegetation and bottom sediments. The model can be run on microcomputer with Fortran compiler. The model applied to t wo small streams which are located in U.S.A., and Canada. The model re sults compared well with observed data. The dispersion parameter was c omputed by the model.
