Rivers of Ljubljana

The Sava is a river in Central and Southeast Europe, a right-bank and the longest tributary of the Danube. From its source in Slovenia, it flows through Croatia and along its border with Bosnia and Herzegovina, and finally reaches Serbia, feeding into the Danube in its capital, Belgrade.

The Ljubljanica (), known in the Middle Ages as the Leybach, is a river in the southern part of the Ljubljana Basin in Slovenia. The capital of Slovenia, Ljubljana, lies on the river. The Ljubljanica rises south of the town of Vrhnika and flows into the Sava River about downstream from Ljubljana. Its largest affluent is the Mali Graben Canal. Including its source affluent the Little Ljubljanica (), the river is in length. The Little Ljubljanica joins the Big Ljubljanica () after and the river continues its course as the Ljubljanica.

The Iška () is a river of central Slovenia. Part of the river valley—the Iška Gorge or Iška Canyon ()—separates Lower Carniola from Inner Carniola. The river is long. After flowing past Strahomer, the river follows an almost straight line and joins the Ljubljanica River, and therefore belongs to the Sava and Black Sea basins.

The Gradaščica is a river in Slovenia. The river is long. It begins in Polhov Gradec at the confluence of Little Creek () and Big Božna Creek. Near Vrhovci it is joined by Horjulščica Creek (also known as Horjulka Creek). Not far past Bokalce, most of the stream is split off into the Mali Graben and the rest continues as the Gradaščica (also known as the Mestna Gradaščica 'Town Gradaščica'). This continues through the Vrhovci neighborhood into the Vič District, where it is joined by Glinščica Creek, before continuing into the Trnovo District and emptying into the Ljubljanica.
