Yadenitsa
The Yadenitsa is a 26 km-long river in southern Bulgaria, a right tributary of the river Maritsa.
Geography
The river takes its source under the name Kurtovsko Dere at an altitude of 1,992 m, about 1.7 km north of the now abandoned Hristo Smirnenski Refuge in the Chakaritsa locality, eastern Rila mountain range. It initially flows southwards and southeast of the refuge turns east, and then northeast in a narrow steep valley that forms the orographic boundary between the major mountain ranges Rila and Rhodope. At the village of Golyamo Belovo the Yadenitsa valley widens and 3 km downstream it flows into the Maritsa at an altitude of 317 m near the town of Belovo.Its drainage basin covers a territory of 138 km2 or 0.26% of Maritsa's total.
The river has snow-rain feed with high water in April–May and low water in September. The average annual discharge at Belovo is 1.25 m3/s.
