The pressurized pipelines: The risk of bidirectional fluid exchange with the environment / Cevovodi pod pritiskom i rizik od razmene fluida sa okolinom
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The pressurized pipeline fluid transport is supposed to be cheap, reliable and efficient. If buried, pipelines are hard observable by means of leaks, minor cracks and asset damages. These phenomena can influence both the ...
Маркетиншки приступ искоришћењу влажних земљишта / Marketinški pristup iskorišćenju vlažnih zemljišta
(Jugoslovensko društvo za zaštitu voda, 2004)
Захваљујући бројним улогама у хидролошком циклусу, кружењу и задржавању хемијских и био-лошких материја и очувању биолошке разноврсности, влажна земљишта представљају ресурс којим би се могле задовољити различите људске ...
Uticaj širine i položaja breše na konzervativnost računske sheme MacCormack / Effect of breach width and position on mass conservation property of MacCormack numerical scheme
(Građevinsko-arhitektonski fakultet Niš, 2002)
U ovom radu analizira se uticaj širine i položaja breše na svojstvo konzervativnosti računske sheme Makormak (MacCormack). Svojstvo konzervativnosti ispituje se praćenjem relativne greške zapremine nastale numeričkom ...
Possible application of self-compacting concrete / Mogućnost primene samozbijajućeg betona
(Univerzitet u Novom Sadu - Građevinski fakultet, Subotica, 2007)
The results of laboratory testing of self-compacting concrete (SCC) made with a new-generation superplasticizer are presented in this paper. The testing was performed both in normal curing conditions (specimens cured in ...
Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja / Application of 2D and 3D modelling in bay entrance design
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2007)
Najveći problem zaliva je zasipanje - prirodan proces koji se ne može izbeći. Visoki troškovi održavanja zaliva (bagerovanja mulja i čišćenja obala) nameću potrebu primene mera za smanjenje uvlačenja nanosa u zaliv. Budući ...
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, ...
SWAT-based runoff modeling in complex catchment areas: Theoretical background and numerical procedures
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
This paper shows the structure of the SWAT-based model used in modeling of the 'rainfallrunoff' process. The SWAT model is hydro-dynamic and physically-based model for application in complex and large basins. Model inputs ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
Comparative analysis of hydrological drought definition methods / Uporedna analiza metoda za definisanje hidroloških suša
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Basic methodology of RUN and TIPS methods, developed and introduced by prof. V. Yevjevich, are presented in this paper. The application and practical aspects of the expanded versions of those methods to the drought event ...
Numerical modeling of a steep chute with curvature in plane / Numeričko modeliranje brzotoka u krivini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Two-dimensional (2D) open-channel flow models for a steep chute with curvature in plane are developed. TVD McCormack and TVD MUSCL method have been used to facilitate an easy-to-use code. The performances of the numerical ...
