Long-term thermal two- and three-dimensional analysis of roller compacted concrete dams supported by monitoring verification
(Canadian Journal of Civil Engineering, 2010)
This paper presents two-dimensional (2D) and three-dimensional (3D) numerical models for unsteady phased thermal analysis of RCC dams. The time evolution of a thermal field has been modeled using the actual dam shape, RCC ...
Ski jump design
(Proceedings of the Institution of Civil Engineers-Water Management, 2010)
This paper is concerned with ski jump design for overflow dams and chute spillways. Despite the vast scope of literature on this subject, research in this field is still needed. Three important issues are addressed: take-off ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
Analytical models of confluences: A survey and models' assessment / Pregled i ocena analitičkih modela ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Assumptions upon which development of 1D models of free-surface flow rest are not valid at open-channel junctions. Thus, the 1D flow equations cannot be used for calculation of upstream flow depths, or water levels in a ...
Pressure drop test as a hydroinformatic tool for preliminary network topology validation
(IWA Publishing, 2019)
Usage of the appropriate model of water distribution systems (WDS) enables easier everyday operations and management decisions. Creating a reliable model of WDS requires a large amount of system response data for different ...
The role of conceptual hydrologic model calibration in climate change impact on water resources assessment
(IWA Publishing, 2016)
Assessment of climate change (CC) impact on hydrologic regime requires a calibrated rainfall-runoff model, defined by its structure and parameters. The parameter values depend, inter alia, on the calibration period. This ...
A simple numerical method for snowmelt simulation based on the equation of heat energy
(IWA Publishing, 2016)
This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its ...
Detekcija nivoa u laboratorijskim kanalima primenom tehnike obrade slika
(Srpsko društo za odvodnjavanje i navodnjavanje, 2019)
Određivanje i praćenje promena nivoa vode u laboratorijskim uslovima primenom tradicionalnih mernih metoda opterećeno je raznim nedostacima: tačnost, frekvencija uzorkovanja, inertnost mernog uređaja i osetljivost na spoljne ...
A normalized regression based regional model for generating flows at ungauged basins
(Water Science and Technology, 2013)
Revision of existing methodologies for generating monthly-flow series at ungauged basins based on multivariate nonlinear correlation has led to a simple two-parameter model. While the existing methodology used hydrological, ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Srpsko hemijsko društvo, Beograd, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
