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, ...
Identification of leak characteristics in pipe systems by dynamic monitoring
(Integrating Water Systems - Proceedings of the 10th International on Computing and Control for the W, 2010)
The paper presents some reflections about use of hydraulic transients in identification of pipe system characteristics. Controlled and safe transients can be used to excite pipe network to respond to change in flows/pressures. ...
Application of 3D numerical models in confluence hydrodynamics modelling
(University of Illinois at Urbana-Champaign, 2012)
In this paper performance of the SSIIM2 model (3D finite-volume model with the k-ε-type turbulence model closure) in confluence hydrodynamics modelling is assessed using the published experimental ...
Management of Multipurpose Resources Systems in Areas Vulnerable to Floods
(Macedonian Committee on Large Dams, 2019)
Floods are natural events that have occurred since the earliest times, endangering people, their settlements and property. As a consequence of climate changes and changes in the catchment area (changes in land use, ...
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 ...
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 ...
Role of upstream planform curvature at asymmetrical river confluences–laboratory experiment revisited
(Kubaba Congress Department and Travel Services, 2008)
River confluence hydrodynamics is influenced by different controls such as the junction angle, bed elevation discordance between incoming streams, upstream planform curvature, momentum ratio values of the confluent streams, ...
Effect of bed elevation discordance in the main river on the confluence hydrodynamics in 90 degrees straight-channels' confluences
(CRC Press/Balkema, 2014)
A role of the difference in bed elevations in the main-river (Delta z(MR)) at its entrance to a 90 degrees straight-channels' confluence is studied numerically using a 3D finite-volume model. Three characteristic hydrological ...
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. ...
