Sliv reke Crnice zauzima područje centralnog dela Srbije. Smešten je između opštine Paraćin na zapadu, Sisevačkog basena na istoku, sliva Ravanice na severu i Jovaničke reke na jugu. Na razmatranom području dominantnu ulogu ima karsni tip izdani, koga karakteriše nestabilan režim u pogledu oscilacija izdašnosti i nivoa podzemnih voda. Na osnovu prethodno sprovedenih opita obeležavnja na ponoru Nekuvoda i Brezovice dokazana je podzemna veza sa slivom reke Crnice, čime je dokazano da je hidrogeološka površina sliva u znatnoj meri veća u odnosu na hidrološku (topografsku). Primenom alata u okviru ArcGIS programa, izvršeno je sračunavanje površine sliva koja u konkretnom slučaju iznosi 397 km2, a dobijeni rezultati iskorišćeni su kao osnova za sračunavanje parametara bilansne jednačine. Monitoring oticaja sliva ove reke uspostavljen je od strane Republičkog hidrometeorološkog zavoda Srbije još davne 1926. godine i traje, sa nekoliko prekida, do danas. U radu će biti data i analiza režima proticaja reke Crnice za ukupni osmatrački period, kao i za izdvojene 30-to godišnje periode (1931-1960, 1961-1990, 1991-2020). Takođe
urađena je i autokorelaciona analiza za pomenute, izdvojene 30-to godišnje periode.

The Crnica river basin occupies the area of the central part of Serbia. It is located between the municipality of Paraćin in the west, the Sisevački basin in the east, the Ravanica basin in the north and the Jovanička river in the south. In the considered area, the dominant role is played by the karst aquifer, which is characterized by an unstable regime in terms of oscillations in disharges and groundwater level. Based on the previously conducted dye tracer tests on the Nekuvodo and Brezovica sinkholes, an underground connection with the Crnica river basin was proven, which proved that the hydrogeological area of the basin is significantly larger than the hydrological (topographic) one. Using tools within the ArcGIS program, the basin area was calculated, which in this case is 397 km2, and the obtained results were used as a basis for calculating the parameters of the balance equation. Monitoring of the drainage of this river basin was established by the Republic Hydrometeorological Institute of Serbia as early as 1926 and continues, with a few interruptions, to this day. The paper will also provide an analysis of the flow regime of the Crnica River for the total observation period, as well as for selected 30-year periods (1931-1960, 1961-1990, 1991-2020). An autocorrelation analysis was also performed for the mentioned, separated 30-year periods.
