Sažetak
The water supply in the town and region of Vara_din is based on the exploitation of groundwater. Chemical analysis of groundwater samples, sampled during the past 20 years, indicates an increase of nitrate concentration. In order to identify the origin of nitrates and to enable improvement of the present situation, a pollutant transport simulation has been worked out. In this study a unsteady groundwater flow and transport model, with variable boundary conditions was developed. The model was based on a random walk particle tracking method. The groundwater quality has been measured over a period of more than 15 years which supplied enough information to calibrate the model. The result of the numerical modelling was definition of nitrates distribution which fractions come from fertilization, farms and as infiltration from a river.
