INFLUENCE OF STRESS RATIO IN SHEAR SURFACE ON SHEAR STRENGTH OF DEPOSITED MATERIAL
The "Ribnica" landfill of the "Vrtlište" surface mine bordered the river Ribnica until during 2017, a landslide was started and the river Ribnica was interrupted, and a water reservoir was formed. After the completion of the tunnel that diverted the river Ribnica, its previously interrupted riverbed in the downstream part is planned for continuatio...

ANALYSIS OF TIME OSCILLATIONS OF WATER ON LAKE MODRIC AS A MULTI-PURPOSE RESERVOIR
The major task of multi-purpose reservoir „Modrac“ operation is to decide how much water should be released now and how much should be retained for future use given some available and/or forecasted information at the beginning of the current time period. In practice, reservoir operators usually follow rule curves, which stipulate the actions that s...

A NEW MODEL FOR PRODUCED WATER TREATMENT IN ELEMIR OIL FIELD
The oil reservoirs of the southeastern part of the Panonian basin are characterized by considerable presence of water,i.e.waterdrive. The hydrocarbon reservoirs are mostly in the middle and final production stages. The water production is especially significant in wells producing with an installed Electrical Submersible Pump (ESP). As production co...

THE ANALYSIS OF WATER RELEASE FROM THE HYDRO ACCUMULATION LAKE MODRAC WITH SPILLWAY CURVE AND VOLUME CURVES
Dam Modrac is multiple arched reinforced concrete buttress dam, with nine buttresses and ten arches, which by its technical characteristics and volume of the accumulation is considered as one of the high dams. Crown level of spillway is 200.00 m a.s.l. Crest length is 205.00 m, while the maximum height is 27.50 m. To control the water level in the ...

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 poll...
