Continuous monitoring or computational estimation of pollutant level along Somes River has to be increased, because it is related to the increase in industrial and live-stock farms activity along the river. These could represent an important threat on surrounding ecosystems and human health. Our paper is dealing with spatio-temporal modeling of pollutant dispersion in surface rivers, taking into consideration real situations of river pollution, e.g. the past cyanide discharge in Somes River, Romania (well known and surveyed at international level) in 2000. The study consists in a series of pollution scenarios that happen every day or could happen along the river. These events are described by means of 1D and 2D analytical models.
First of all a pollution and hydrodynamic study of Somes River was carried out. The pollution sources, the main pollutants, the factors influencing river behavior and the characteristic parameters of the river were determined. Simulation parameters account for real experimental values. Physical and chemical transformation processes were also considered and suitable models for real pollutant discharge situation were realized.
The models make possible the evaluation of river length affected by pollution and to estimate the pollution degree (through pollutants predicted concentrations), pprovide information about river behavior, pollutants concentration in water and pollution wave evolution in time and space. Simulation results were compared with the results obtained using commercial acknowledged software for Somes River.
