Numerical Simulation of 3D Flow at Right-angled Confuence with and without Upstream Planform Curvature
(Chemical Industry Press, Beijing, 2010)
This paper aims at studying the effect of upstream planform curvature on the flow in the confluence hydrodynamics zone. To do this, a 3D numerical model is used for simulation of flow at right-angled
confluences with ...
Method for water distribution systems reliability evaluation
(International Environmental Modelling and Software Societey, 2004)
A new methodology for water resources systems reliability evaluation is presented. The proposed methodology considers both: mechanical reliability (probability of pipe failure) and reliability of hydraulic parameters in ...
Benefits of Green Infrastructure for Flood Mitigation in Small Rural Watersheds—Case Study of the Tamnava River in Serbia
(Springer Nature Singapore, 2022)
A consideration of climate change in recent years shifted the focus on re-evaluation of classical flood protection measures in riverine systems. While the conventional, grey infrastructure measures have their established ...
Decision support system for Iron Gate hydropower system operations
(Contemporary Water Management: Challenges and Research Directions, 2022)
Today, hydropower systems operate in highly competitive environment. Thus, it is important for them to get
maximum benefits out of existing assets, resources and constraints as well. In order to make the best possible ...
Identification of homogeneous regions for runoff estimation in ungauged basins
(11th International Multidisciplinary Scientific Geoconference (Sgem 2011), Vol II, 2011)
This paper addresses the problem of defining appropriate characteristic which leads to homogeneous regions identification, required for application of multiple nonlinear regression methodology for interpolation of hydrologic ...
Climate change in Serbia and adaptation measures in the field of water resources management
(Slovenian Committee on Large DamsMacedonian Committee on Large Dams, 2020)
The paper presents the actual situation in the field of water, especially water as a resource. With an average amount of domestic water of about 1700 m3 per capita per year, Serbia is one of the poorest countries in Europe. ...
Long-term change in hydroclimatic regimes in catchments across Serbia
(Faculty of Geography, Lomonosov Moscow State University, 2023)
This study presents trend analyses in several catchments across Serbia. The trend analyses are preformed over series of precipitation, temperature and streamflows. These variables are represented by different indicators, ...
Flow measurement methodology for low head and short intake bulb turbines - Iron Gate 2 case
(International group for hydraulic efficiency measurement (IGHEM), 2022)
Flow measurement of low head turbines, with short intakes like bulb turbines is challenging since there is no “regular” cross-section with fully developed velocity profile. In most situations the flow data during field ...
Uncertainty assessment of flow measurements at Iron Gate 2
(International group for hydraulic efficiency measurement (IGHEM), 2022)
To allow for the reliable hydraulic efficiency estimation of the tubular turbines before and after their revitalization at the Hydro Power Plant (HPP) Iron Gate 2, a novel flow measurement system was designed and tested ...
