Abstract
In order to keep the pollution levels below permissible limits and also to forecast
the final concentrations to be reached, current patterns and dispersion
characteristics are required for water quality problems in lakes and coastal
regions. In this case, it is necessary to solve the dispersion equations that include
transport, diffusion and reaction processes to find the distribution and
concentrations of pollutant.
In this study, a numerical model was developed for simulating pollutant
dispersion in well-mixed lakes and reservoirs. The model is based on solving
dispersion equation using the Newton-Raphson algorithm and results of
hydrodynamic model. The developed model can be used for long-term
distribution of conservative or non-conservative pollutants in lakes and
reservoirs.
