Natural Radioactivity of Intrusive-Metamorphic and Sedimentary Rocks of the Balkan Mountain Range (Serbia, Stara Planina)
(MDPI AG, 2018)
Stara Planina (also known as the Balkan mountain range) is known for numerous occurrences and deposits of uranium and associated radionuclides. It is also famous for its geodiversity. The geologic framework is highly ...
Automatic, semi-automatic and manual validation of urban drainage data
(Water Science and Technology, 2010)
Advances in sensor technology and the possibility of automated long distance data transmission have made continuous measurements the preferable way of monitoring urban drainage processes. Usually, the collected data have ...
Aspects of water velocity measurements with acoustic Doppler velocimetry / Aspekti merenja brzine vode akustičnom Dopler anemometrijom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The paper analyzes the various aspects of acoustic Doppler anemometry usage, for the measurements of instantaneous water velocity, in the context of the problems of hydraulic engineering. Physical principle of the measuring ...
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 ...
The effects of oscillating nozzle on Christiansen's uniformity coefficient
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2015)
Rainfall simulators have been used in research for more than 40 years. Unfortunately, there is not much literature on their construction and calibration. This paper presents a rainfall simulator experimental rig, developed ...
Hydraulic Jumps in Adverse-Slope Stilling Basins for Stepped Spillways
(MDPI AG, 2018)
The performance of flat stilling basins can be inadequate for conditions when the tailwater depth is insufficient for hydraulic jump stabilization. In such cases, adverse-slope stilling basins can be used because they ...
Forecasting of THM concentration in distribution water supplying network / Prognoza sadržaja trihalometana u distribucionoj vodovodnoj mreži
(Savez inženjera i tehničara Srbije, Beograd, 2012)
The presence of free chlorine is a prerequisite for the formation of THM's, The THM concentration increases with extending the reaction time between natural organic matter and disinfectants, which means that these products ...
Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Calibration of a 1D/1D urban flood model using 1D/2D model results in the absence of field data
(Water Science and Technology, 2011)
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface ...
Nitrate removal from water by biological denitrification / Biološka denitrifikacija u pripremi vode za piće
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2011)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
