Ecological risk assessment for different macrophytes and fish species in reservoirs using biota-sediment accumulation factors as a useful tool
(Elsevier Ltd, 2018)
Metal content was evaluated in the sediment, macrophytes and fish in the Medjuvrtje reservoir (Western Serbia). Concentrations of 16 trace elements (Ag; Al; As; B; Ba; Cd; Co; Cr; Cu; Fe; Li; Mn; Ni; Pb; Sr; Zn) were ...
Converging stepped spillway flow
(Taylor and Francis Ltd., 2016)
Wall deflection in supercritical flow induces standing waves which significantly influence the flow field close to the wall. This paper analyses the flow in the converging stepped spillway, using two scale-models with ...
Integrated hydrological information system for northern Algeria
(IAHS-AISH Publication, 2010)
As a result of cooperative work of experts from Algeria (ANRH) and Serbia (Energoprojekt with the assistance of Belgrade University) through the project CRESNA (Carte des Ressources en Eau Souterraines du Nord de l'Algerie), ...
Control theory-based update of water levels in 1D hydrodynamic models
(CRC Press/Balkema, 2020)
Model-driven forecasting used for flood risk assessment or river hydropower
systems management, can produce bad results due to many model uncertainties. False inflow
and lateral inflow data and/or poor estimation of ...
Sensitivity Analysis of a Physically Based Distributed Model
(Springer Netherlands, 2016)
The objective of this study is to perform a sensitivity analysis of the SHETRAN model on the example of the torrential Lukovska River catchment in Serbia. The sensitivity analysis of the model was performed for the following ...
3D numerical simulation of cross-levee breaching process due to overtopping flow
(CRC Press/Balkema, 2016)
Dike failures due to overtopping flows cause severe damages. For risk management, it is of great importance to understand the mechanism of dike failure and predict flows and sediment transport in the breaching process ...
The validation of stormwater biofilters for micropollutant removal using in situ challenge tests
(Elsevier, 2014)
Stormwater harvesting is becoming a popular alternative water resource in water stressed regions. Stormwater biofilters have been recognized as being among the most promising pre-treatment technologies. In this study, a ...
Numerical modeling of dissolved oxygen recovery during aeration in lakes
(Environmental Hydraulics - Proceedings of the 6th International Symposium on Environmental Hydraulic, 2010)
One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen.A numerical model has been developed for simulation ...
Numerical simulation of 3D flow at 90o straight-channel confluence with bed elevation discordance
(TuTech Verlag, TuTech Innovation GmbH, 2012)
The paper aims at studying the effect of difference in bed elevations between the tributary and main canals (∆zT) on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for flow simulation ...
Managing energy costs in water distribution systems
(Nis University, 2011)
The reduction of energy consumption is one of the first steps in fighting operational costs in Water Distribution Systems (WDS). Finding the optimal energy savings procedure and its implementation into a real-time control ...
