The Sazliyka or Rakitnitsa (, ; also transliterated Sazlijka or Sazliika) is a river in southeastern Bulgaria, a left tributary of the Maritsa. It originates in the Sarnena Sredna Gora mountain range. In its upper course until Radnevo, it is also known as the Rakitnitsa or Syuyutliyka. The river is 145 kilometres in length
The name is thought to be derived from the Ottoman Turkish saz, "bulrush", with a Bulgarian feminine suffix. The name of its upper course, Syuyutliyka, is also from a Turkish root, söğüt, "Willow", while Rakitnitsa is its Bulgarian translation, the equivalent word for "osier" being rakita.
Geography
The river takes its source under the name Toplitsite at an altitude of 651 m some 1.5 km southwest of the summit of Ruya (812 m) in the
Sredna Gora mountain range. Until the village of Kazanka it flows southwards and then turns east. Downstream of the village of Starozagorski bani the river heads south-southwest and after receiving its tributary the Chatalka turns southeast. It reaches the Upper Thracian Plain at the villages of Lyaskovo and Rakitnitsa. Throughout its course in the mountains its valley is deep and forested. In the plains the riverbed is corrected with protective dikes. In the Upper Thracian Plain the Sazliyka takes several more turns — east downstream of
Arnautito, southeast downstream of Sarnevo and south after
Radnevo. It flows into the
Maritsa at an altitude of 78 m about 1.7 km east of the town of
Simeonovgrad.
The river receives numerous tributaries, the most important being the
Ovcharitsa (72 km), the
Sokolitsa (61 km) and the Blatnitsa (54 km), all of them left.
Its drainage basin covers a territory of 3,239 km2 or 6.1% of the Maritsa's total and borders the drainage basins of the Omurovska reka, Tekirska reka, Martinka and Arpadere to the west and southwest, and the Tundzha to the north and east, all of them left tributaries of the Maritsa.
The Sazliyka has predominantly rain feed with high water in January–April and low water in July–October.
