SILTATION OF MODRAC HYDROACCUMULATION FROM ASPECT OF USABLE VOLUME

Abstract

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 Spreča downstream from
dam and reservoir Lukavac.
