The Ombla (also Umbla or Dubrovačka rijeka ; river from Dubrovnik ) is a karst river in southern Dalmatia in Croatia . It is considered to be one of the shortest rivers in Europe . The Ombla rises as a powerful karst spring in a large cave near the Komolac district about five kilometers as the crow flies north of the city center of Dubrovnik .
Origin of the water
Most of the water in the Ombla is fed by the Trebišnjica River. This seeps away 20 km from the Ombla spring in the lower Popovo polje , near the Croatian border, in several crevice-like seepage points.
Data
Depending on how you look at it, the ombla is between 20 meters and 4.2 kilometers long, but quite wide and very rich in water; on the map it appears as the Adriatic bay north of Dubrovnik. Its mean discharge is 24 m³ / s and fluctuates between 2.8 and 106 m³ / s. The lower part of the river ( draga ) is already flooded by the sea, but can be seen as a clear undersea current. The water depth in this area is up to 30 m. The Ombla is navigable over a length of 3.7 km. Some suburbs of Dubrovnik ( Mokošica , Komolac, Rožat, Prijevor, Lozica ) stretch along the river, whose water has been used in the Dubrovnik waterworks since 1437. The part of the ombla that is not influenced by the sea is only approx. 20 m long. It is located above a weir in close proximity to the source.
