Una (Sava) in the context of "Unac (river)"

The Neretva (pronounced [něreːtʋa], Serbian Cyrillic: Неретва), also known as Narenta, is one of the largest rivers of the eastern part of the Adriatic basin. Four hydroelectric power plants with large dams (higher than 15 metres) provide flood protection, electricity and water storage. The Neretva is recognized for its natural environment and diverse landscapes.

Freshwater ecosystems have suffered from an increasing population and the associated development pressures. One of the most valuable natural resources of Bosnia and Herzegovina and Croatia is its freshwater resource, contained by an abundant wellspring and clear rivers. Situated between the major regional rivers (Drina river on the east, Una river on the west and the Sava river) the Neretva basin contains the most significant source of drinking water.

Bosanska Krupa (Serbian Cyrillic: Босанска Крупа) is a city located in the Una-Sana Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina. As of 2013, it has a population of 29,659 inhabitants.

It is situated on the banks of river Una in northwestern Bosnia and Herzegovina, 30 km (19 mi) northeast from Bihać (350 km away from Sarajevo).

The Iapodes (or Iapydes, Japodes; Greek: Ἰάποδες and Ἰάπυδες; Serbo-Croatian: Japodi) were an ancient people who dwelt north of and inland from the Liburnians, off the Adriatic coast and eastwards of the Istrian peninsula. They occupied the interior of the country between the Colapis (Kupa) and Oeneus (Una) rivers, and the Velebit mountain range (Mons Baebius) which separated them from the coastal Liburnians. Their territory covered the central inlands of modern Croatia and Una River Valley in today's Bosnia and Herzegovina. Archaeological documentation confirms their presence in these countries at least from 9th century BC, and they persisted in their area longer than a millennium. The ancient written documentation on inland Iapodes is scarcer than on the adjacent coastal peoples (Liburni, Delmatae, etc.) that had more frequent maritime contacts with ancient Greeks and Romans.

The Iapodes had their maximal development and territorial expansion from the 8th to 4th centuries BC. They settled mostly in inland mountain valleys between Pannonia and the coastal Adriatic basin, but in disputation with southern Liburni they periodically reached also the northern Adriatic coast at Vinodol valley (classical Valdevinum).

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 Sava is 990 kilometres (615 miles) long, including the 45-kilometre (28 mi) Sava Dolinka headwater rising in Zelenci, Slovenia. It is the largest tributary of the Danube by volume of water, and the second-largest after the Tisza in terms of catchment area (97713km²) and length. It drains a significant portion of the Dinaric Alps region, through the major tributaries of Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut and Krka. The Sava is one of the longest rivers in Europe and among the longest tributaries of another river.

The Austro-Turkish War, also known as the Habsburg–Ottoman War, was fought from 1788 to 1791, between the Habsburg monarchy and the Ottoman Empire. During the conflict, Habsburg armies succeeded in taking Belgrade (1789) and liberating much of central Serbia, also capturing several forts in central Croatia and in the Pounje region of the Ottoman Bosnia. Much of those gains were lost in the later stages of the war, that ended by the Treaty of Sistova (1791), with minor territorial changes in favor of the Habsburg side. The war was fought concomitantly with the Russo-Turkish War (1787–1792).

The canton is bordered by Republika Srpska from the east, the Canton 10 from the southeast, and Croatia from the south, west, and north. The majority of the population is Bosniak (90%).

Bihać is a city and the administrative centre of Una-Sana Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina.
