AB  - U radu je razmatrano osamnaest pokazatelja malih voda u šesnaest profila hidroloških stanica u slivu Južne Morave. Pokazatelji su ocenjeni statističkom analizom i grupisani u hidrološke i ekološke pokazatelje. Sračunata je korelacija između svih pokazatelja. Ekološki protoci u profilima hidroloških stanica dobijeni su metodom GEP. Pokazatelji malih voda su prebačeni na dva neizučena profila korišćenjem regresije sa geo-morfološkim karakteristikama sliva. Podešavanje vrednosti ekološkog protoka u neizučenim profilima urađeno je na bazi pripadnosti slivova donora hidrogeološkim regionima u izučavanoj oblasti.
AB  - Eighteen low flow indicators are considered in the research of sixteen hydrological stations in the Južna Morava river basin. The indicators are estimated by statistical analysis and grouped as hydrological and environmental indicators. A cross-correlation between all indicators is assessed. Environmental flows at hydrologic stations are obtained by the GEP method. The environmental low flow indicators are transferred to two small ungauged basins by regression with physiographic characteristics. The adjustment of environmental flows at ungauged basins is performed according to locations of the donor stations in the hydrogeological regions of the studied area.

AB  - U radu je sprovedena analiza prosečnog godišnjeg oticanja za Mali, neizučeni sliv Tulovske reke, u slivu Južne Morave. Primenjene su metoda Turka, metoda Langbajna i regionalni izrazi za dobijanje prosečnog oticaja. Kao ulazni podaci korišćene su srednje temperature, prosečne godišnje padavine na slivu i srednja nadmorska visina sliva. Proračuni su sprovedeni korišćenjem različitih klimatoloških ulaznih podataka, a rezultati su zatim upoređeni. Podaci o padavinama i temperaturi dobijeni su iz digitalnog repozitorijuma projekta CarpatClim u rasterskom formatu, prostorne rezolucije 10 km x 10 km. Korišćene su i vrednosti osmotrene na meteorološkim stanicama RHMZ. Razlike u vrednostima rasterskih i osmotrenih klimatoloških podataka pripisane su uticaju visinske razlike terena, koji rasterski podaci nisu bili u stanju da obuhvate. Analize su pokazale da procenjene vrednosti oticaja mogu da se razlikuju do 50% u zavisnosti od odabira metode i ulaznih podataka.
AB  - An analysis of mean annual runoff was conducted for a small ungauged catchment of the Tulovska River in the South Morava River Basin. Langbein's method, Turk's method and regional regression models were applied for obtaining the mean runoff. Long-term mean temperature, annual precipitation and the mean catchment elevation are used as input data. The estimations were conducted using various sources of climatological input data and the results were then compared. Precipitation and temperature data were derived, in a 10 km x 10 km resolution raster data format, from the digital data repository of the CarpatClim project. Point measurements of temperature and precipitation by the Republic Hydrometeorological Service of Serbia were also used as input data and compared with the raster data. The difference between the raster and point meteorological data was attributed to the effects of terrain elevation spatial variability, not captured in the raster data. The analyses showed that the predicted mean runoff can differ up to 50%, depending on the chosen method and the input data.

AB  - Koncept pragova percepcije uveden u okviru novih preporuka za ocenu velikih voda u SAD - Biltenu 17c, namenjen je predstavljanju protoka u godinama bez podataka osmatranja. U radu se na uzorku od 9 stanica sa potpunim nizom osmatranja na teritoriji Srbije, utvrđuje pogodnost korišćenja tri visine donjeg praga percepcije, na osnovu karakteristika nepotpunih nizova. Ispitano je ukupno 160 nizova. Nepotpuni nizovi su formirani na tri načina, izostavljanjem podataka od jedne do dvadeset godina u kontinuitetu, na različitim mestima u osmotrenom nizu. Rezultati upućuju na malu osetljivost na visinu primenjenih donjih pragova percepcije svih ocenjenih kvantila velikih voda na ispitivanim stanicama na Dunavu, Savi i Velikoj Moravi. Kod četiri ispitivane stanice srednje površine sliva (1000-8000 km2), kvantili velikih voda su uglavnom potcenjeni. Za stanice sa identifikovanim donjim izuzecima, bez obzira na površinu sliva, bolji rezultati su dobijeni za niži donji prag percepcije.
AB  - The concept of perception thresholds has been introduced as a part of new guidelines for flood frequency assessment in the U.S. - Bulletin 17c with intention to present missing flow data. The paper investigates the suitability of using three values as the lower perception threshold based on the characteristics of incomplete series in 9 stations in Serbia with complete datasets. A total of 160 datasets were analyzed. Incomplete datasets are formed in three ways, creating gaps from one to twenty consecutive years, at different locations in the observed dataset. The results indicate low sensitivity to the value of the applied lower perception threshold for all estimated flood quantiles at the studied stations on the river Danube, Sava and Velika Morava (area  gt  30000km2 ). In the four examined stations of the medium catchment area (~1000-8000 km2 ), the underestimated flood quantiles prevail. At stations with detected low outliers, regardless of the catchment area, better results were obtained for the smaller lower perception threshold value.
