Air-water flow on a labyrinth spillway
(Serbian Water Pollution Control Society, Belgrade, 2014)
The design of the Beni Slimane Dam (Medea Province, Algeria) was verified by scale model analyses, conducted on two separate scale models: a partial model of labyrinth spillway and a complete model of spillway structures. ...
GIS Based Estimation of Sediment Discharge and Areas of Soil Erosion and Deposition for the Torrential Lukovska River Catchment in Serbia
(Kluwer Academic Publishers, 2014)
In the present study the SHETRAN river basin modelling system was used in conjunction with Geographic Information System (GIS) to estimate potential erosion and deposition rates within the catchment and the concentrations ...
Estimating demands for water supply under reduced pressure / Procena ukupnih potreba za vodom pri smanjenju pritiska
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
Many water utilities, continue to operate inefficient water distribution systems (WDSs) with a significant amount of water and revenue losses. This paper investigates the potentials of the available pressure management ...
Subsidence due to lowering groundwater level / Sleganje kao posledica sniženja nivoa podzemne vode
(Savez građevinskih inženjera Srbije, Beograd, 2014)
Subsidence due to lowering groundwater level, is often neglected problem. Detailed description of the problem is presented in the paper and model for calculating subsidence is elaborated. Model calculates vertical one ...
Shaft spillway with deflector downstream of vertical bend
(Thomas Telford Services Ltd, 2014)
This study considers the hydraulic design of a shaft spillway with a constriction at the upstream end of the vertical bend. The effect of key factors relating to the capacity of the crest, shaft and tunnel is assessed using ...
Long-term changes of annual and seasonal flows: A case of the Sava River / Dugoročne promene godišnjih i sezonskih proticaja - primer reke Save
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
This paper investigates the long-term changes in the hydrological time series. For this purpose, we use the trend analysis. The trend analysis is performed by using the standard Mann-Kendall trend test and by using the ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Challenging analytical task: analysis and monitoring of arsenic species in water
(Environmental Engineering and Management Journal, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
