KRKA, a river in Dalmatia; springs out at the western foot of Dinara Mountain and flows into the sea near Sibenik; length 72.5 km. In the parts of the course where the Krka flows through marly soils, certain extensions are created (Arandelovac, etc.). In limestone it forms a narrow and deep canyon (up to 200 m), flowing over travertine barriers and creating waterfalls. In the upper course are two 10-m high waterfalls. At the entrance of the Krka into the Knin field is a waterfall called Veliki Buk (20 m).

In the lower part of the course are the waterfalls: Bilusic (19.6 m), Prijen (15 m), Manojlovac (three waterfalls; 84.5 m), Roski Slap (25.5 m) and Skradinski Buk (37.5 m), the most beautiful of all. Between Roski Slap and Skradinski Buk is Visovac Lake (13 km long) with an islet (see Visovac). Downstream of Skradinski Buk is the Krka river estuary (about 20 km long), in which freshwater mixes with saltwater. Part of the estuary is also Prukljansko Lake. The waterfalls were used for the production of electric power.
