Water storage reservoirs and their role in the development, utilization and protection of catchment
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2011)
Reasons why water storage reservoirs are necessary in accordance with the sustainable development strategy are described in the paper. The main positive and negative impacts of reservoirs on the environment are analyzed. ...
Uticajni činioci na rečnim ušćima sa izdignutim dnom pritoke / Controls at river confluences with discordant beds
(Savez građevinskih inženjera Srbije - Beograd, 2011)
U ovom radu se pomoću modela prostornog tečenja ispituje uticaj četiri izabrana činioca na hidrodinamiku ušća sa izdignutim dnom pritoke. To su: ugao uliva 'alfa', odnos sila inercije reke i pritoke MR, odnos [irina korita ...
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 ...
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 ...
New method for complex water resources systems reliability evaluation / Novi pristupi pri određivanju pouzdanosti složenih vodoprivrednih sistema pod pritiskom
(Savez građevinskih inženjera Srbije, Beograd, 2011)
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 ...
Low cost arsenic removal from aqueous solution by adsorption / Uklanjanje arsena iz vode adsorpcijom na nekonvencionalnim materijalima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
This paper deals with arsenic removal from water by adsorption with unconventional materials: natural materials (zeolite, bentonite, sepiolite, limonite, pyrolusite), waste materials (waste iron slag, waste sand filter) ...
Pregled i ocena analitičkih modela ušća / Analytical models of confluences: a survey and models’ assessment
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2011)
Na spojevima otvorenih tokova strujnice postaju zakrivljene, jer vertikalno ubrzanje fluidnih delića nije zanemarljivo u odnosu na ubrzanje zemljine teže, pa su to mesta gde ne važe osnovne pretpostavke na kojima se zasnivaju ...
Stresses in the upstream cutoff zone of concrete gravity dams / Naponsko stanje u zoni uzvodnog zuba gravitacione betonske brane
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Upstream cutoff in the concrete gravity dam foundation is introduced as a general stability measure in the beginning of the 20-th century. It become widely accepted in design practice in the late 50-ties. Nevertheless, ...
Criteria for water well design / Kriterijumi za proračun i projektovanje izdašnosti bunara
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2011)
Sufficient water well yield is a result of both hydrogeological characteristics of the media and well construction - its design and installation. The choice of water well design and construction materials is influenced by ...
Effects of slope and surface orientation on calculation of reference evapotranspiration based on Penman-Monteith equation / Uticaj nagiba i orijentacije površine na proračun referentne evapotranspiracije primenom Penman-Monteith metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Evapotranspiration is an important component of hydrological balance and it is calculated based on reference evapotranspiration (ET0). In the last fifty years there have been many empirical models developed for determining ...
