Subterranean Rivers
A subterranean river (also known as an underground 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. Some natural rivers may be entirely subterranean, collecting in and flowing through cave systems. In karst topography, rivers that originate above ground can disappear into sinkholes, continuing underground until they reappear on the surface downstream, possibly having merged with other subterranean rivers. The longest subterranean river in the world is the Sistema Sac Actun cave system in Mexico. Subterranean rivers can also be the result of covering over a river or diverting its flow into culverts, usually as part of urban development.Richard J. Heggen: Und ...

Cavefish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, Troglomorphism, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 Species description, scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many species have very small ranges and are Threatened species, threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkans, Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The prevailing currents flow counterclockwise from the Strait of Otranto. Tidal movements in the Adriatic are slight, although acqua alta, larger amplitudes occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because it collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures ...

Ombla
The Ombla is a short river in Croatia, northeast of Dubrovnik. Its course is approximately long, and it empties into the Rijeka Dubrovačka, ria formed by the Adriatic Sea near Komolac in Dubrovnik-Neretva County. Rijeka Dubrovačka is actually a ria, a flooded river valley formed through changes in sea surface elevation on a geologic time scale. The river rises as a karst spring fed by groundwater replenished by Trebišnjica, which is an influent stream flowing in Popovo Polje, in the immediate hinterland of the Ombla. The elevation difference between the river's source and its mouth is just over . The average discharge of the river is per second. The drainage basin of the Ombla encompasses and, besides the short surface course, includes only groundwater flow. The Ombla is used as a source of drinking water for Dubrovnik's water supply network, and construction of a hydroelectric power plant has been planned for the past two decades. , the plans entail construction of ...

Krupa (Neretva)
The Krupa ( sr-Cyrl, Крупа) river is a left tributary of the river Neretva and the main water current of Hutovo Blato, which leads the waters from Gornje Blato and Svitavsko Lake into the Neretva river near Dračevo. The length of Krupa is 9 km with an average depth of 5 meters. The Krupa is an extension and outlet of Deransko Lake. Also, the Krupa is a unique river in Europe, because the river flows both ways. It flows normally from the source to the mouth and from the mouth to the source. This happens when, due to high water levels and large quantities of water, the Neretva pushes the Krupa river in the opposite direction. The river has rich biodiversity, with numerous fish species endemic to the Neretva basin inhabiting Krupa and its lakes. It is observed that important '' Salmo marmoratus'', known under its vernacular name as ''glavatica'' and/or ''gonjavac'', and endemic to the handful of rivers of the Adriatic watershed, enters these waters to spawn.

Trebišnjica
The Trebišnjica ( sr-cyrl, Требишњица) is a river in Bosnia and Herzegovina, and the right tributary of the Neretva.

With a total length of above the ground, and roughly another below the surface, the Trebšnjica river is one of the longest sinking rivers in the world with the total of above and under the ground. In hydrological terms, it represents a sub-basin within the Neretva river basin. In classical antiquity, the river was known as the Arion, Sources The Trebišnjica river originate near town of Bileća.

Caves Entranceexit
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
