The Topčiderka river flows into the Sava, in the Bay of Čukarica, just south of the fair complex, while Novi Beograd and the peninsula of Mala Ciganlija are just across the Sava, which is at this point the narrowest (200 meters).
The Rakovički potok (Serbian Cyrillic: Раковички поток, English: Rakovica Creek) is a short stream in north-central Serbia, a 8,5 kilometer-long right tributuary to the Topčiderka river.
