Ponor
A ponor is a natural opening where surface water enters into underground passages; they may be found in Karst topography, 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 Spring (hydrology), springs, similar to estavelles. Morphologically, ponors come in forms of large pits and caves, large fissures and caverns, networks of smaller cracks, and sedimentary, Alluvium, alluvial drains. Etymology The name for the karst formation ponor comes from Croatian language, Croatian and Slovene language, Slovene. It derives from the proto-Slavic language, proto-Slavic word ''*nora'', meaning ''pit'', ''hole''. Several places in southeast Europe (Bulgaria, Croatia, Czech Republic, Hungary, Romania, Montenegro, Slovenia) Ponor (other), bear the name ''Ponor'' due to associated karst openings.

Risle
The Risle (; less common: ''Rille'') is a long river in Normandy, left tributary of the Seine. The river begins in the Orne department west of L'Aigle, crosses the western part of the department of Eure flowing from south to north and out into the estuary of the Seine on the left bank near Berville-sur-Mer. Its upper valley is part of the Pays d'Ouche, its lower valley separates the regions of the Lieuvin and Roumois. The Risle is regarded as a coastal river. Fishing is common downstream at Pont-Audemer. The river and surrounding areas are parts of a protected Natura 2000 site called Risle, Guiel, Charentonne. On July 30, 2012, the Risle vanished in a ponor between La Ferrière-sur-Risle and La Houssaye. It runs underground for . Its only major tributary is the Charentonne. The Risle flows through the following departments and communes: *Orne: Sainte-Gauburge-Sainte-Colombe, L'Aigle *Eure Eure ( ; ; or ) is a department in the administrative region of Norma ...

Karst Topography
Karst () is a topography formed from the dissolution of soluble carbonate rocks such as limestone and Dolomite (rock), dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's Oil and gas reserves and resource quantification, hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems.

Reka River
The Reka (literally, 'river' in Slovene), also the Inner Carniola Reka (), is a river that starts as Big Creek () in Croatia, on the southern side of Mount Snežnik, and flows through western Slovenia, where it is also initially known as Big Creek (). The river is long, of which is in Slovenia. At the village of Škocjan it disappears underground through Škocjan Caves, flowing underneath the Slovenian Karst. The river continues as part of the Timavo in Italy. Tracer studies have shown that it also feeds springs elsewhere on the Adriatic Coast between Trieste and Monfalcone Monfalcone (; Venetian language#Regional variants, Bisiacco: ; ; ; archaic ) is a town and (municipality) in the Province of Gorizia, Regional decentralization entity of Gorizia in Friuli-Venezia Giulia, northern Italy, located on the Gulf of Tr ....

Polje
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. Geology A polje, in geological terminology, is a large, flat-floored depression within karst limestone, whose long axis develops in parallel with major structural trends and can become several miles (tens of kilometers) long. Superficial deposits tend to accumulate along the floor. Drainage may be either by surface watercourses (as an ''open polje'') or by swallow holes (as a ''closed polje'') or ponors. Usually, the ponors cannot transmit entire flood flows, so many poljes become wet-season lakes. The structure of some poljes is related to the geological structure, but others are purely the result of lateral dissolut ...

Slovenia
Slovenia, officially the Republic of Slovenia, is a country in Central Europe. It borders Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and a short (46.6 km) coastline within the Adriatic Sea to the southwest, which is part of the Mediterranean Sea. Slovenia is mostly mountainous and forested, covers , and has a population of approximately 2.1 million people. Slovene language, Slovene is the official language.

Logatec
Logatec (; , ) is a town in Slovenia. It is the seat of the Municipality of Logatec. It is located roughly in the centre of Inner Carniola, between the capital Ljubljana and Postojna. The town of Logatec has seen rapid industrial development and immigration since the completion of the nearby A1 motorway to the coast. Name The name ''Logatec'' is of Celtic origin, probably derived from Celtic ''*longatis'' 'ferryman, boatman', from the Proto-Celtic word ''*longā'' 'ship', thus meaning 'ferrymen's settlement'. The name became ''Longaticum'' in Latin, which was borrowed into Slavic as ''*Lǫgatьcь''. Early attestations of the Slavic name include ''Logach'' in 1265 (and ''Logatzc'' in 1296, ''Logatsch'' in 1307, ''Logacz'' in 1319, and ''de Logas'' in 1354). History The earliest mentions of the settlement are from Roman times (Roman way station ''Mansio Longatico''). The vicinity of trade routes between the interior and the coast has always played an important part in the region. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Škocjan Caves
Škocjan Caves (; , ) is a cave system located in Slovenia. Škocjan Caves was included on UNESCO’s list of natural and cultural World Heritage Sites in 1986. Škocjan Caves is a significant underground phenomenon on the Karst Plateau and in Slovenia. After gaining independence from Yugoslavia in 1991, Slovenia made a commitment to actively protect the Škocjan Caves area. To fulfill this commitment, Škocjan Caves Regional Park was established, along with its managing authority, the Škocjan Caves Park Public Service Agency. Description Škocjan Caves is an underground phenomenon in the Karst region and Slovenia. It was designated as Ramsar wetlands of international importance on May 18, 1999. Along with the underground stream of the Reka River, it forms one of the longest karst underground wetlands in Europe. The explored length of the caves is . The caves have formed in a layer of Cretaceous and Paleocene limestone. At the Big Collapse Doline (), the Reka River dis ...
