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 ...
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, ...
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, ...
Incorporation of water storage reservoirs into the environment
(Macedonian Committee on Large Dams, 2013)
The construction of large dams and creation of water storage reservoirs have significant effect on the environmental and social surrounding. Although these impacts have been recognized in the first stage of modern dam ...
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 ...
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 bed elevation discordance at 90? straight-channel confluences
(River Flow 2012 - Proceedings of the International Conference on Fluvial Hydraulics, 2012)
This paper aims at studying the role of difference in bed elevations between the tributary and main canals (z T) in 90 confluence under different hydrologic/hydraulic conditions. To do this, 3D finitevolume model is used. ...
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 ...
