Abstract

The paper presents a dynamic simulator tool designed for predicting effects of the pollutant accidental discharge in a segment of the river Some. The first approach considers the pollutant source distributed along the river bank and the second one the pointwise discharged pollutant in the river stream. The accidental release of the pollutant is considered either constant or varying with time. The complex time and space distribution of the pollutant concentration is revealed by the simulator. The k-epsilon turbulence model of the flow has been used and the advection-dispersion-reaction processes have been considered. Further, the effects of adding a neutralizing agent in certain points of the river segment are investigated with the aim of reducing the downstream pollutant concentration. The influence of the neutralizing agent discharge position and concentration are investigated in order to counteract the pollutant spreading effect in the river.
