This is a list of karst springs. There are different types of karst springs, including inversacs (or estavelles), Vauclusian springs, vruljas, and others. All of them form in limestone settings. [1]
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word cave can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called exogene caves. Caves which extend further underground than the opening is wide are called endogene caves.
Karst is a topography formed from the dissolution of soluble carbonate rocks such as limestone, dolomite, and gypsum. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. More weathering-resistant rocks, such as quartzite, can also occur, given the right conditions.
An aquifer is an underground layer of water-bearing material, consisting of permeable or fractured rock, or of unconsolidated materials. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude, which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could lead to the formation of a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer.
An atoll is a ring-shaped island, including a coral rim that encircles a lagoon. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical parts of the oceans and seas where corals can develop. Most of the approximately 440 atolls in the world are in the Pacific Ocean.
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ponor, swallow hole or swallet. A cenote is a type of sinkhole that exposes groundwater underneath. Sink and stream sink are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock.
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.
A cenote is a natural pit, or sinkhole, resulting when a collapse of limestone bedrock exposes groundwater. The term originated on the Yucatán Peninsula of Mexico, where the ancient Maya commonly used cenotes for water supplies, and occasionally for sacrificial offerings. The name derives from a word used by the lowland Yucatec Maya—tsʼonoʼot—to refer to any location with accessible groundwater.
The Woodville Karst Plain Project or WKPP, is a project and organization that maps the underwater cave systems underlying the Woodville Karst Plain. This plain is a 450-square-mile (1,200 km2) area that runs from Tallahassee, Florida, U.S. to the Gulf of Mexico and includes numerous first magnitude springs, including Wakulla Springs, and the Leon Sinks Cave System, the longest underwater cave in the United States. The project grew out of a cave diving research and exploration group established in 1985 and incorporated in 1990.
Boulder clay is an unsorted agglomeration of clastic sediment that is unstratified and structureless and contains gravel of various sizes, shapes, and compositions distributed at random in a fine-grained matrix. The fine-grained matrix consists of stiff, hard, pulverized clay or rock flour. Boulder clay is also known as either known as drift clay; till; unstratified drift, geschiebelehm (German); argile á blocaux (French); and keileem (Dutch).
Glaciokarst is a geological term that refers to a specific type of karst landscape that been influenced significantly by past glacial activity.
A foiba — jama in South Slavic languages scientific and colloquial vocabulary — is a type of deep natural sinkhole, doline, or sink, and is a collapsed portion of bedrock above a void. Sinks may be a sheer vertical opening into a cave or a shallow depression of many hectares. They are common in the Karst (Carso) region shared by Italy and Slovenia, as well as in a karst of Dinaric Alps in Bosnia and Herzegovina, Montenegro and, Croatia. The foibe massacres, a war crime that took place during and after World War II, take their name from the foibe.
Weeki Wachee Springs is a natural tourist attraction located in Weeki Wachee, Florida, where underwater performances by "mermaids," women wearing fish tails as well as other fanciful outfits, can be viewed in an aquarium-like setting in the spring of the Weeki Wachee River. A waterpark, Buccaneer Bay, river boat rides, kayak and paddleboard rental are some of the other activities offered at Weeki Wachee Springs.
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.
The Santa Fe River is a 75-mile (121 km) river in northern Florida. The watershed of the river is approximately 1,380 square miles (3,574 km2) and spreads across southern Columbia, southern Suwannee, western Bradford, far southern Baker, Union, northern and eastern Gilchrist, and northern Alachua counties. The headwaters of the river are Lake Santa Fe, near Keystone Heights. The Santa Fe River is usually a slow-flowing river. This slow speed, combined with the abundant leaf-drop from nearby trees, especially Bald Cypress, leads to a very dark-brown river due to dissolved tannins.
Zacatón is a thermal water-filled sinkhole belonging to the Zacatón system - a group of unusual karst features located in Aldama Municipality near the Sierra de Tamaulipas in the northeastern state of Tamaulipas, Mexico. At a total depth of 339 meters (1,112 ft), it is one of the deepest known water-filled sinkholes in the world.
The Temenica is a river in Slovenia. It is one of the most typical influent streams of Slovenia's karst terrain.
Karst Underwater Research (KUR) is a registered 501(c)(3) non-profit organization that specializes in the research and documentation of karst aquifers and their corresponding surface features. KUR members perform a variety of scientific processes, including mapping and cartography, radio location, photography, videography, YSI water analysis and sampling.
Jarrod Michael Jablonski is a pioneering technical diver and record setting cave diver as well as an accomplished business owner and operator. These business operations include Halcyon Manufacturing, Extreme Exposure Adventure Center and Global Underwater Explorers. In July 2021 Jablonski launched and now operates the world's deepest pool at Deep Dive Dubai. Jablonski is one of the main architects behind the 'Doing It Right' system of diving.
A karst spring or karstic spring is a spring that is part of a karst hydrological system.
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.
