Assessment of the impact of bend type on flow characteristics in 180° compound bends
(Faculty of Civil Engineering - SkopjeГрадежен факултет – Скопје, 2021)
River bends are rarely simple, i.e., the bend radius is rarely constant throughout the bend length. They are rather irregular, i.e. their shape in the plan can be approximated with different bend radii. Since the bulk of ...
Influence of small water storage reservoirs on reliability of irrigation water supply
(Macedonian Committee on Large Dams, 2021)
The paper analyses the consequences of climate change on the irrigation water demand and the impact of water storage reservoirs on increasing the reliability of irrigation water supply. Analyses were performed for the Vrbas ...
Velocity field and discharge measurements at the turbine inlet of Iron Gate 2 hydropower plant
(European Geosciences Union/Copernicus Publications, 2021)
To define the performance characteristics of turbines in Hydropower Plants (HPP) accurate hydraulic, mechanical and electrical quantities are needed. The discharge is the most difficult quantity to measure and assess its ...
A New Fractal Approach to Account for Capillary and Adsorption Phenomena in the Water Retention and Transfer Properties of Unsaturated Soils
(Wiley, 2020)
To describe the water retention and transfer properties of an unsaturated soil over the whole range of matric suction, it is necessary to account for both capillary and adsorption phenomena. Existing models combine well-known ...
Report on application of sectorization method for creation of District Meter Areas (DMAs) within the water distribution network of the city of Amsterdam
(The University of Sheffield., 2020)
The subject of this report is presentation of abilities of sectorization algorithm to identify and create District Meter Areas (DMAs) within the water distribution network of the city of Amsterdam.
District Meter Area ...
Procena krive protoka i rekonstrukcija poplavnog talasa u dubokom koritu sa uskim plavnim površinama / Estimation of the stage-discharge curve and reconstruction of the flood hydrograph in a deep river channel with narrow floodplains
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2021)
U ovom radu razmatra se svrsishodnost primene metode razmene količine kretanja za procenu krive protoka i rekonstrukciju talasa velikih voda u dubokim koritima za veliku vodu koja imaju uske plavne površine. Ovo pitanje ...
Hydrological indicators of the riverbed incision along the free-flowing Danube River reach from Budapest to Slankamen relevant for the lateral connectivity between the river channel and floodplains
(Catholic University of Eichstätt-Ingolstadt, 2021)
Hydrological regime plays a primary role in the sustainable management of floodplains, as floodplain ecosystem dynamics and balance are largely dependent on the dynamics of the flow regime of rivers. In the 1980’s a drying ...
Metoda za odredjivanje protoka na ulazu u turbine HE "Djerdap 2"
(Srpsko društvo za odvodnjavanje i navodnjavanje i Akademija inženjerskih nauka Srbije, 2021)
Protok vode kroz turbinu je jedna od najznačajnijih veličina u postupku upravljanja radom agregata, ali je istovremeno i veličina koju je najteže pouzdano izmeriti. Merna nesigurnost je obično veća nego kod merenja ostalih ...
Određivanje protoka na prilazima cevnih turbina uz pomoć EM senzora brzine: Određivanje nesigurnosti izmerenog protoka / Discharge measurements at the tubular turbine intakes with EM current meters: Assessment of the discharge measurement uncertainty
(Univerzitet u Beogradu – Građevinski fakultet, Beograd, 2021)
Određivanje hidrauličke efikasnosti turbina se zasniva na pouzdanom poznavanju nekoliko osnovnih hidrauličkih, mašinskih i elektro veličina. Iz ove grupe, protok vode kroz turbinu je veličina koju je najteže pouzdano ...
Water level and discharge measurements in: Metrology in Urban Drainage and Stormwater Management: Plug and Pray
(IWA Publishing, 2021)
The knowledge of water levels and discharges in urban drainage and stormwater management (UDSM) systems is of key importance to understand their functioning and processes, to evaluate their performance, and to provide data ...
