A review of the most commonly used methods for ungauged catchments flood flow estimation in Serbia
(12th International Multidisciplinary Scientific Geoconference, Sgem 2012, Vol. III, 2012)
This paper summarizes findings on the flood flow estimation in ungauged catchments during the last decade in Serbia. The method used for synthetic unit hydrograph ise well known in hydrological practice as SCS method. ...
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 ...
Influence of organic acid treatement on recycled concrete aggregate
(XIV International Scientific Conference iNDiS 2018 and Subconference "Eco build", 2018)
As a result of increasing global environmental awareness and sense of responsibility for future generation lives, utilization of demolition waste as potential aggregate for structural concrete has been proposed. Reducing ...
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 ...
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. ...
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, ...
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, ...
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 ...
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 ...
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 ...
