Male vode na malim i srednjim slivovima Srbije

Abstract

U radu se prikazuju rezultati statističke analize izabranih parametara malih voda na malim i srednjim slivovima u Srbiji nastali tokom izrade nove monografije „Prosečni protoci i male vode na malim i srednjim slivovima Srbije”, koju zajednički realizuju Institut za vodoprivredu „Jaroslav Černi“ i Republički hidrometeorološki zavod Srbije uz učešće Građevinskog fakulteta iz Beograda i Građevinsko-arhitektonskog fakulteta iz Niša. Osnovna ideja je da se na odabranim srednjim i malim slivovima u Srbiji definišu osnovne kvantitativne karakteristike prosečnih protoka i malih voda. Bazni podaci koji su korišćeni su zvanični podaci Republičkog hidrometeorološkog zavoda sa 132 profila hidroloških stanica na srednjim i malim slivovima na teritoriji Srbije južno od Save i Dunava. Pri tome su korišćene sve raspoložive vremenske serije srednjednevnih i minimalnih godišnjih protoka. Periodi obrade su bili od početka rada određene hidrološke stanice do zaključno sa 2018. godinom. U ovom radu dat je grafički prikaz rezultata obrade osnovnih karakteristika malih voda i to: minimalnih srednjemesečnih protoka verovatnoće pojave 95%, kao i minimalnih godišnjih protoka verovatnoće pojave 1%.

The paper presents the results of the statistical analysis of selected low flow indicators in medium and small Serbian basins obtained withing the scope of a new monograph "Mean and low flows in medium and small basins of Serbia", which is being prepared jointly by the Water Institute "Jaroslav Cerni" and the Republic Hydrometeorological Service of Serbia, with the participation of the Faculty of Civil Engineering of Belgrade and the Faculty of Civil Engineering and Architecture of Nis. The basic idea is to provide principal quantitative characteristics of mean and low flows in selected medium and small basins in Serbia. The data used in the analysis are the official data provided by the Republic Hydrometeorological Service at 132 stream gauges in medium and small basins in the territory of Serbia, south of the Sava and Danube Rivers. Thereby, all the available time series of mean daily and annual minimum flows were used. The processing periods are from when the certain gauging station started operating to the end of 2018. This paper presents only the results of the basic low flow indicators, such as the minimum mean monthly flows of the 95% probability of exceedance, as well as the annual minimum flows of the 1% probability of non-exceedance.
