SILTATION OF MODRAC HYDROACCUMULATION FROM ASPECT OF USABLE VOLUME
Modrac hydroaccumulation is the largest and most important multi-purpose water resource for water supply to large industrial capacities of importance for Bosnia and Herzegovina, but also for public water supply of Tuzla and Lukavac. Since the water quality of the hydroaccumulation is threatened by the waste water of a large number of different pollutants in the basin area of 1.189 km², and that the useful volume of hydroaccumulation is limited, then during the time it comes to the filling of the hydroaccumulation dominated by coal dust from coal mines in the basin reservoirs. It must be ensured that good quality water is supplied to consumers, especially households and industries, while ensuring hydrobiological minimum dilution of waste water discharged into the river Spreca downstream from dam and reservoir Lukavac.
