Trebišnjica in the context of "Trebinje"

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.

Banjani (Serbian Cyrillic: Бањани) was a tribe in Old Herzegovina, and historical region in western Montenegro. Its territory comprises 380 km (150 sq mi), west of Nikšić, in the centre between Nikšić and Bileća, from the top of Njegoš mountain to the Trebišnjica river, and on to the Bileća Lake. All Banjani families have Jovanjdan (St. John's feast day, January 20) as their slava (a Serbian Orthodox tradition).
