Ein Dreihundert-Meter-Siphon in der Seehhle von Tapolca (Ungarn)., 1961, Kessler, H.

Ein Dreihundert-Meter-Siphon in der Seehhle von Tapolca (Ungarn), 1961, Kessler, H.

Karst-hydrological researches in Hungarian caves., 1965, Kessler Hubert
Although Hungary does not belong to the large Karst countries, extensive speleologic and karst-hydrologic investigations are carried out. On the one hand, Hungary owns one of the largest stalactite caves in the world, on the other hand the majority of raw materials and the connected industries are linked with Karst regions which pose particular water supply problems. The largest water supplying caves are in the North of Hungary. The best known cave is the Aggtelek cave with a length of 22 km, but there are numerous other, recently disclosed caves of a length of 1-5 km, which were discovered by way of artificial means and on the basis of many years of hydrologic observations. Of particular interest are the active thermal caves with waters of 30C. In one of these latter a diver discovered and measured a siphon of a length of 300 m. By way of experiment, speleotherapic treatments were applied in some of these caves. By calculation of decades of series of measures an applicable formula was established for the calculation of the percent of seepage in the Karst regions. In several of these caves the influence of precipitation on the intensity of stalactite formation was measured. The indication of the so-called ,,year-rings" in the stalactites furnishes data concerning precipitation of bygone millenaries, which are also valuable for the investigation of periods. In several caves the changes in ion concentration of the water currents was measured and the correlation with the cross section of the caves was determined. On the basis of complex measurements in Karst sources the possibility of disclosing hitherto unknown cave systems arises. In this manner, recently several caves were artificially discovered.

Preliminary note on the Algae of Crystal Cave, Kentucky., 1965, Nagy J. P.
Collections of a preliminary type carried out in Crystal Cave, Kentucky, resulted in the identification of seven algal taxa. A Chamaesiphon (Dermocarpales) and an Asterocytis (Bangioidea) are reported for the first time from a speleo-environment. As no correlation could be found among the algae occurring in Crystal Cave and those of nearby Mammoth Cave the conclusion is reached that the cave algal floras do not originate from the algal vegetation of the surface but may have gotten into the caves at the time of the latter's formation.

100m-Siphon der Koppenbrllerhhle bei Obertraun (Obersterreich) durchtaucht., 1969, Hasenmayer J. , Wunsch A.

Drought and Murray Cave, Cooleman Plain, 1969, Jennings J. N. , Nankivell I. , Pratt C. , Curtis R. , Mendum J.

The drought culminating in 1967-68 opened water-traps in Murray Cave, thus permitting the re-exploration and survey in January 1968, of a further 1,000 feet of the main passage. Previous explorations, of which oral tradition persisted, are known to have taken place in 1902-3 and some details of the early visitors are presented. The characteristics of the extension are predominantly shallow phreatic in nature and about half of it episodically functioning in this way at the present time; the water-traps along it are inverted siphons in the strict sense and located at the sharpest changes in cave direction. The exploration limit consists of a rockfall beneath a doline, which appears, therefore, to be at least in part a collapse doline. Beneath two other dolines the cave has no sign of collapse, though tall avens reach towards the surface; these dolines are due to surface solution only. The forward part of the cave is overlain by a short, steep dry valley; the relationship between the two remains problematic but there is good reason not to regard the dry valley as the determinant of the cave's location. The evidence is now stronger for an earlier hypothesis that the cave was formerly the outflow cave of nearby River Cave, a perennially active stream cave. It also seems likely that the episodic activity of Murray Cave is due to flood overflow from River Cave. The hydrological regime of the cave is compared with precipitation records of the nearby stations. The episodic flow through the cave does not require an abnormally wet winter; it can follow fairly quickly after complete emptying of the water-traps and approaches an annual event. Draining of the water-traps is a much less frequent event, but whether a series of low rainfall years is necessary, or a single pronouncedly dry year is sufficient to achieve this, cannot be determined from available data. On either count, it seems probable that the cave opened up two or more times between the known occasions of 1902-3 and 1968 in the period 1909-53 when the cave was visited infrequently.

Le siphon de la Fuentona de Muriel (Soria, Espagne), 1987, Sanz Perez E. , Medina_ferrer J.
THE SIPHON OF FUENTONA DE MURIEL (SORIA SPAIN) - The present paper deals with the description of the siphon of Fuentona de Muriel (Soria Spain), the deepest submerged cave in Spain, associated with a karstic spring of 1 m3/s mean flow. This spring drains a carbonated aquifer of Upper Cretaceous with a syncline geometrical form.

RHYTHMIC KARST SPRINGS, 1991, Bonacci O, Bojanic D,
Rhythmic springs (ebb and flow springs, intermittent springs, potajnice) belong to the group of springs which appear exclusively in karstified terrains. The paper describes various types of rhythmic springs and gives their classification. It also develops a mathematical model for the functioning of this type of springs based on the principle of recharge and emptying of the underground reservoir through siphon action. Applying this model, according to the observed hydrographs of some rythmic springs in Yugoslavia, the paper explains in detail the structure of the underground reservoir located in the karst

The Spring Cave Gojak., 2001, Kuhta M. , Jalzic B. , Novosel A.
The speleological diving investigation of the cave Gojak spring were performed during five investigation periods which lasted in total ten days. With the total investigated length of 2166 m the cave Gojak spring is one of the most important speleological phenomena in Croatia and the longest caves investigated behind a submerged siphon. The general strike of the cave is in the south-western direction towards Ogulin and the system ?ulin ponor-Medvednica. The width of up to 20 m of the Main channel (Glavni channel) of the cave makes it a unique example of a subsurface water flow in karst that is 756 m long. The channel terminates with a siphon lake 25 m deep. The large dimensions of the submerged part of the channel indicate a possibility of successful diving through this obstacle and would allow further investigations of the cave. The most distant point reached from the entrance along the main channel in a straight line is 575 m, and the elevation difference of water levels is approximately 10.5 m. In a morphological sense the cave Gojak spring is a branched speleological object. This is confirmed by the fact that 1410 m of underground channels or 65% of the total cave length was investigated in satellite channels. Since there are possibilities of further investigation of some satellite channels this ratio will grow. During the speleological investigations it was determined that in this part of the underground karst system there are no significant accumulations of waste and other material which would prevent groundwater flow, especially for the currents from the ?ulin ponor. In the cave only individual samples of rapping were found. The samples of rapping are old since they are not in use today. It can be concluded that this finding indicates to an existence of a obstruction in the underground between the ?ulin ponor and the spring which acts as a filter for the new generation of disposed waste but they are located upstream from the investigated part of the cave channels. It is presumed that the results of this investigation, and the possibility of further advance along the main and satellite channels, as well as geological and hydrogeological features of this cave induce further investigations which will allow better understanding of the unique karst underground in the wider region of Ogulin.

Modes de positionnement topographique et lectromagntique dun siphon. Exemple du Qattine Azar (Liban), 2002, Courbon, Paul
Topographical and electromagnetic positioning of a deep sump: Qattine Azar (Lebanon) - Wasting, pollution, climatic modifications, urbanisation and demographic explosion will generate a serious water scarcity in many countries, among them, the Middle East. In Lebanon, after the discovery of an important underground river, is established a water impounding project, needing a 280 meters drilling through limestone. The author describes the topographic method used to survey the cave and to set up the future drilling. The survey has been confirmed by an electromagnetic positioning ARCAS (radiolocation) perfected by Joan Erra. The accuracy of the two determinations is estimated.
