Hydrodynamic analysis of radial collector well ageing at Belgrade well field
The origin and effect of hydraulic resistances on the rate of ageing of radial collector wells are identified through numerical hydrodynamic analysis. The research includes hydrodynamic modeling of one such well with new laterals at Belgrade well field. The performance of the laterals is aggravated by rapid ageing. The change in the hydraulic parameters of the laterals during the first decade of operation is analyzed through simulations of the groundwater regime with realistically specified geometries and hydraulics of the ...Đorđije Božović, Dušan Polomčić, Dragoljub Bajić, Jelena Ratković.

Imputing missing data using grey system theory and the biplot method to forecast groundwater levels and yields
Groundwater management is one of today’s important tasks. It has become necessary to seek out increasingly reliable methods to conserve groundwater resources. Dependable forecasting of the amounts of groundwater that can be abstracted in a sustainable manner requires longterm monitoring of the groundwater regime (rate of abstraction and groundwater levels). Monitoring of the groundwater source for the town of Bečej, Serbia had been disrupted for multiple years. The objective of the paper is to assess the possibility of reinterpreting ...Jelena Ratković, Dušan Polomčić, Zoran Gligorić, Dragoljub Bajić.

Probabilistic analysis of anisotropic rock slope with reinforcement measures
During the construction of E75 highway through Grdelica gorge in Serbia, a major failure occurred in the zone of reinforced rock slope. Excavation was performed in highly anisotropic Paleozoic schist rock formation. The reinforcement consisted of the two rows of micropile wall with pre-stressed anchors. Forces in anchors were monitored with load cells while benchmarks were installed for superficial displacement measurements. The aim of the study is to investigate possible causes of instability considering different probability distributions of the ...Zoran Berisavljević, Dušan Berisavljević, Miloš Marjanović, Svetlana Melentijević.

Analiza hidrauličke veze između reke Save i podzemnih voda na izvorištu za vodosnabdevanje Obrenovca
Na izvorištu „Vić bare“ formiranom u aluvijonu Save za vodosnabdevanje Obrenovca u poslednje dve decenije izvedeno je više detaljnih hidrogeoloških istraživanja u cilju utvrđivanja rezervi podzemnih voda i izdvajanja zona sanintarne zaštite. Monitoring podzemnih voda u celoj zoni izvorišta, za potrebe izrade hidrodinamičkog modela, omogućio je i hidrauličku analizu odnosa površinskih voda reke Save i podzemnih voda na izvorištu sa kojeg se trenutno zahvata do 310 l/s vode.
