A subterranean river is a river or watercourse that runs wholly or partly beneath the ground, one where the riverbed does not represent the surface of the Earth. It is distinct from an aquifer, which may flow like a river but is contained within a permeable layer of rock or other unconsolidated materials. A river flowing below ground level in an open gorge is not classed as subterranean.
The Dinaric Alps, also Dinarides, are a mountain range in Southern and Southcentral Europe, separating the continental Balkan Peninsula from the Adriatic Sea. They stretch from Italy in the northwest through Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, and Kosovo to Albania in the southeast.
A polje, also called karst polje or karst field, is a large flat plain found in karstic geological regions of the world, with areas usually in the range of 5–400 km2 (2–154 sq mi). The name derives from the Slavic languages, where polje literally means 'field', whereas in English polje specifically refers to a karst plain or karst field.
Vjetrenica is the largest cave in Bosnia and Herzegovina, and the most biodiverse cave in the world. It is part of the Dinaric Alps mountain range, which is known for its karstic and speleological features. The cave is located in the Popovo field in Ravno, East Herzegovina in the Federation of Bosnia and Herzegovina.
A losing stream, disappearing stream, influent stream or sinking river is a stream or river that loses water as it flows downstream. The water infiltrates into the ground recharging the local groundwater, because the water table is below the bottom of the stream channel. This is the opposite of a more common gaining stream which increases in water volume farther downstream as it gains water from the local aquifer.
The Trebišnjica is a river in Bosnia and Herzegovina, and the right tributary of the Neretva. Before it was utilized for hydro exploitation via various hydrotechnical interventions and systems with different purposes, Trebišnjica used to be a sinking river, rising and sinking through its course before resurfacing at various places from the Neretva river below the Čapljina to the Adriatic coast, and along the coast from the Neretva Delta to Sutorina.
Popovo Polje (Serbo-Croatian: Popovo polje / Попово поље, pronounced[pɔ̌pɔʋɔpɔ̂ʎɛ], is a polje in Bosnia and Herzegovina, located in a southernmost region of the country, near the Adriatic coast. Its size is 5.9 square kilometres.
Badanj Cave is located in Borojevići village near the town of Stolac, Bosnia and Herzegovina. This rather small cave has come to public attention after the 1976 discovery of its cave engravings, that date to between 12,000 and 16,000 BC.
A ponor is a natural opening where surface water enters into underground passages; they may be found in karst landscapes where the geology and the geomorphology is typically dominated by porous limestone rock. Ponors can drain stream or lake water continuously or can at times work as springs, similar to estavelles. Morphologically, ponors come in forms of large pits and caves, large fissures and caverns, networks of smaller cracks, and sedimentary, alluvial drains.
Mostarska Bijela or simply Bijela is a mountain creek and gorge in Bosnia and Herzegovina. Despite its low discharge and relatively short flow, this river takes a significant place in Bosnia and Herzegovina's Dinaric karst's geology and hydrology.
Šator is a mountain in the Dinaric Alps, in the western regions of Bosnia and Herzegovina. The name šator means "tent". The highest peak Veliki Šator is 1,872 m (6,142 ft) above sea level. Dimensions of the mountain are some 15 km in the west–east and 10 km in the north–south direction.
Kučaj is a mountain range in eastern Serbia. Its highest peak, Velika Tresta has an elevation of 1,284 meters above sea level. They belong to the Serbian extension of Carpathians, which separate the valleys of Great Morava and Timok.
The Rama is a river in Bosnia and Herzegovina, and a major tributary of the Neretva. It joins it from the right by discharging into Neretva's artificial reservoir, Jablaničko lake, at place called Marina Pećina, near village of Gračac, between location of underground powerhouse of Rama Hydroelectric Power Station and Jablanica Dam, depending on water level in Jablaničko lake, some 15 kilometers upstream from Jablanica.
Gatačko polje is a polje within the Gacko municipality in Bosnia and Herzegovina, spanning 57–60 km2, being ca. 24 km long and ca. 3,6 km wide, in the northwest–southeast direction. It is situated between the mountains of Bjelašnica and Lebršnik on the altitude of 930 to 1000 m. The subterranean rivers of Gračanica and Mušnica cross the field. The only larger settlement is Gacko. Near the field are the mountains and straddle of Čemerno, the source of the Trebišnjica, Klinje Lake and the Sutjeska National Park. The field develops agriculture and animal husbandry.
The Zalomka is a karstic river in the southern part of Bosnia and Herzegovina, and as part of the Neretva river system it is one of the largest sinking rivers in the country and Dinarides. It rises under the Morine plateau, near Brajićevići village in Gacko municipality, but also collects its upper course waters from Gatačko Polje.
Vilina Pećina is a cave and a karst resurgence wellspring in Dinaric Alps karst of Bosnia and Herzegovina, also previously known from research descriptions of older date as "Vilić Pećina", such as one from 1896, conducted by Austria-Hungary geologists.
Trebišnjica wellspring-group is a system of two geographically and hydrologically distinct principal groupings of strong karstic springs, Trebišnjica and Čeplica, which together constitute source of the Trebišnjica river. Wellsprings are located just below town of Bileća in Bosnia and Herzegovina. The entire area where founts are situated is submerged under Bilećko Lake since 1967, formed after the construction of Trebinje-1 Hydroelectric Power Station and its large arch dam at Grnčarevo village.
