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 ...
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) ...
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, ...
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 ...
Flow measurement at the short structures in hydraulic complex conditions: HE 'Djerdap 2' case study / Merenje protoka na kratkim objektima u hidraulički neregularnim uslovima na primeru HE 'Đerdap 2'
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Hydraulic conditions at short structures in most cases prevents the existence of cross sections with parallel streamlines and fully developed turbulent flow profile. In such conditions the flow measurement is rather ...
Possible use of hydropower potential of cooling water at the thermal power plant / Mogućnost korišćenja hidroenergetskog potencijala vode za hlađenje termoelektrana
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Possibility of using hydropower potential of cooling water at the thermal power plant with open cooling system is presented in the paper. Cooling water flows gravitationally to the recipient - the river. In the periods of ...
Method for determining the environmental flow downstream of the dams and water intakes / Određivanje potrebnih protoka nizvodno od brana i rečnih vodozahvata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
One of the key design decisions when planning water resources systems with water storage reservoirs and water intakes is to define environmental flow that should be discharged downstream. Terms: environmental flow, water ...
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 ...
Nonparametic estimation of density functions in hydrology / Neparametarske funkcije raspodele u hidrologiji
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
As an alternative procedure for parametric methods in statistical analysis, non-parametric methods are emerging mainly because of their flexibility and ability to completely automate the estimation of probability density ...
