Velocity contours of Coatzacoalcos River rain and dry season over time Modeling of pollutant transport This section presents some of the simulated parameters. Initially we describe the simulation scenario solved to provide a better idea and understand clearly what the simulations are representing. Simulation scenario To assess the water quality in Coatzacoalcos River a representative discharge scenario was initially defined highlighting the main activities and characteristics over this area Fig. 12 . The idea was study the river environmental behaviour influenced by the oil activity developed on this area six discharges where located representing the industrial activity and the influence of urban areas where such facilities industry are seated. The discharge conditions for every simulated water quality parameter are presented in Table 3. Discharge Temp. C DO mg L BOD mg L Faecal Col.
