Polje
A polje, also karst polje or karst field, is a large flat plain found in karstic geological regions of the world, with areas usually . The name derives from the Slavic languages and literally means 'field', whereas in English ''polje'' specifically refers to a karst plain or karst field. In 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 dissolution and planation. The development of poljes is fostered by any blockage ...

Livanjsko Polje
Livanjsko polje (), located in Bosnia and Herzegovina, is the largest ''polje'' ( karstic field) in the world. A typical example of karst polje encircled by tall peaks and mountain ranges, the field is characterized by many unique natural phenomenons and karstic features.

Duvno
Tomislavgrad (), also known by its former name Duvno (), is a town and municipality located in Canton 10 of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina. It mainly covers an area of the historical and geographical region of Tropolje. As of 2013, it has a population of 33,032 inhabitants. In the Roman times it was known as Delminium. During the middle ages when it was part of Croatia and Bosnia, the town was known as Županjac, a name that remained until 1928, when it was changed to Tomislavgrad.

Popovo Polje
Popovo field ( sh-Latn-Cyrl, separator=" / ", Popovo polje, Попово поље, , ) is a ''polje'' ( karstic field) in Bosnia and Herzegovina, located in a southernmost region of the country, near the Adriatic coast. Its size is . Popovo polje is one of the largest ''polje'' (karstic plains) in Bosnia and Herzegovina and the world, famous for its karstic phenomenons and features, and particularly the Trebišnjica river, which flows through the polje as the largest sinking river (also ''losing stream'', or ''influent stream'') in the world, as well as the Vjetrenica cave system, located to the west/south-western parts of the valley.

Ponor
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. Etymology The name for the karst formation ponor comes from Croatian and Slovene. It derives from the proto-Slavic word ''nora'', meaning ''pit'', ''hole'', ''abyss''; the English word ''narrow'' probably has the same origin. Several places in southeast Europe (Bulgaria, Croatia, Czech Republic, Hungary, Romania, Montenegro, Slovenia) bear the name ''Ponor'' due to associated karst openings. Description Whereas a sinkhole (doline) is a depression of surface topography with a pit or cavity directly underneath, a po ...

Nikšić
Nikšić ( cnr, Никшић, italic=no, sr-cyrl, Никшић, italic=no; ), is the second largest city in Montenegro, with a total population of 56,970 located in the west of the country, in the centre of the spacious Nikšić field at the foot of Trebjesa Hill. It is the center of Nikšić Municipality with population of 72,443 according to 2011 census, which is the largest municipality by area and second most inhabited after Podgorica.

Logatec Polje
The Logatec Karst Field or Logatec Polje (; sl, Logaško polje) is a karst field near Logatec in southwestern Slovenia (the traditional region of Inner Carniola). Geographically, it corresponds to the floor of the Logatec Basin ( sl, Logaška kotlina).Oblak-Polajnar, Majda. 1959Logaška kotlina kot geografska individualnost ''Geografski vestnik'' 31: 19–44. It lies at an elevation between and Mihevc, Pavle. 1992. Logaško polje. ''Enciklopedija Slovenije'', vol. 6, p. 312. Ljubljana: Mladinska knjiga. and encompasses about of mostly grassy terrain. Logaščica Creek, a losing stream, runs across the karst field and collects ambient water. The karst field often flooded in the past, and so land improvement was carried out. The northern part of the Logatec Karst Field is called the Empty Karst Field () and the main road from Logatec to Vrhnika runs across it, passing through the linden-lined section known as the Napoleon Avenue ().

Losing Stream
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'' (or ''effluent stream'') which increases in water volume farther downstream as it gains water from the local aquifer. Losing streams are common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth. Losing streams are also common in regions of karst topography where the streamwater may be completely captured by a cavern system, becoming a subterranean river. Examples There are many natural examples of subterranean rivers including: Bosnia and Herzegovina * Unac; Mušnica- Trebišnjica- Krupa/Ombla (Trebišnjica is considered to be one of the largest sinking rivers in the worl ...

Cerknica Polje
Lake Cerknica (; sl, Cerkniško jezero, german: Zirknitzer See) is an intermittent lake in the southern part of the Cerknica Polje, a karst polje in Inner Carniola, a region in southwestern Slovenia. The lake, oriented in the Dinaric direction from northwest to southeast, is present for the most part of the year. When full, it is the largest lake in the country. The plain is surrounded by the Javornik Hills () to the south and Slivnica () to the north, both belonging to Dinaric Alps. The area of the lake mainly reaches , but can reach up to and the surface level varies from to above sea level. The lake is an important wildlife resort, especially as a nesting place for many bird species. Botanically, it is distinguished by amphibious plants. It is therefore a part of two Natura 2000 areas of protection and the focus of the Inner Carniola Regional Park, which covers additional Natura 2000 areas in the broader region.

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, Dolomite (rock), dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, 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 hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German language, German in the late 19th century, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
