Hydrogeologic Constraints on Yucatan's Development, 1974,

Doehring Do, Butler Jh,
The Republic of Mexico has an ambitious and effective national water program. The Secretaria de Recursos Hidraulicos (SRH), whose director has cabinet rank in the federal government, is one of the most professionally distinguished government agencies of its kind in the Americas. Resources for the Future, Inc., has been assisting the World Bank with a water planning study which the Bank is undertaking jointly with the Mexican government. The study is intended to provide guidelines for the development of government policies and projects designed to bring about the most efficient use of Mexico's water resources. However, to date, their study has not been directed toward the growing problems of the northern Yucataan Peninsula which are discussed here.LeGrand (13) suggested that man has inherited a harsh environment in carbonate terranes. In the case of the northern Yucatan Peninsula, the physical environment creates a set of hydrogeologic constraints to future economic and social development. Planning for intermediate and long-range land use on the peninsula must be related directly to the limited and fragile groundwater source. Continued contamination will make future aquifer management a difficult challenge for federal, state, and territorial agencies. We conclude that any strategy for long-range land use in the study area should include establishment of a regional aquifermonitoring network for long-term measurements of key hydrogeologic parameters, including precipitation, evapotranspiration, water table elevations, and water quality. Information from this network would flow into a central facility for storage, interpretation, and analysis. At present the SRH is collecting some of these data. Expansion of the existing program to provide sound information for regional planning will greatly benefit present as well as future generations. If such a program is implemented, it will represent a model for regional planning in other tropical and subtropical karstic terrains

Development of a Subterranean Meander Cutoff: The Abercrombie Caves, New South Wales, 1979,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Frank R. , Jennings J. N.

The Abercrombie Caves are exemplary of a subterranean meander cutoff. The bedrock morphology, especially flat solution ceilings, permits reconstruction of an evolution from slow phreatic initiation to epiphreatic establishment of a substantial throughway, followed by progressive succession to vadose flow and phased channel incision. At two separate stages, there was twofold streamsink entry and underground junction of flow. Five 14C dates from alluvial sediments show that capture of the surface stream was certainly complete before c.15,000 BP and that by c.5,000 BP the stream had almost cut down to its present level.

This is a description of the affinities and biogeographic significance of three new cavernicolous species of Diplopoda from France and Morocco. One species apparently belongs to the Polydesmida (family Paradoxosomidae) and the other two to Craspedosomida (families Caratosphydae and Chordeumidae). 1) Eviulisoma abadi n.sp. is distinguished from other species of this genus by total depigmentation, by the characters of the gonopodial orifice and the male gonopods, by the low number of segments (19) and by its geographic isolation (Morocco) and ecology (Kef Aziza cave). This justifies the establishment of a new sub-genus, Jeekelosoma. The other species of this genus are found in equatorial Africa and the east. E. abadi is the first paleoarctic species of this genus and is the second paleoarctic species of the tribe Eviulisomidi after Boreviulisoma liouvillei Brol.). It is also the first known from a cave. Like the two other known species of Paradoxosomidae known from the southwest of the paleoarctic zone, Boreviulisoma liouvillei Brol. and Oranmorpha guerinii (Gerv.) the new species is indicative of originating in the Ethiopian region at a time when the Sahara was not a barren desert. 2) Ceratosphys maroccana n.sp. from Gouffre Friouato (Morocco) probably is not an epigean troglophile; it is the southernmost species of this genus which is normally found in France and Spain. This is apparently a remnant of a small group of species from the south of Spain that constitute a sub-genus Proceratosphys Mau. and Vincente. 3) Orthochordeumella leclerci n.sp. (caves of Ardche, France) manifest the presence unique in this genus of cavernicolous characters including depigmentation and extreme length of antennae and is the only truly troglobitic species of this genus. Other characters are less distinctive but it is possible to distinguish this species by sexual characteristics from other species, notably that from the neighbouring geographic area, O. cebennica (known only from the Ardche region) which is troglophilic. The other three species are found in epigean forest habitats, one in the Pyrenees, the other two in the Tyrol, the Swiss Jura, Baden and the northeast of France and Belgium.

In 1960 the Slovak Caves Administration, which managed twelve Slovak Caves was founded. It was controlled by the Ministry of Culture of the Slovak Socialist Republic and comprised also the Museum of Slovak Karst and the Slovak Speleological Society; a free speleological organisation. In 1981 such an Administration became part of the State Centre for the Protection of Nature. The main task of this centre was obviously the protection of nature in Slovakia but unfortunately many problems remained unsolved. The social movement in November 1989 accelerated the process to solve such problems and the Forum of Professional Workers of Show Caves was set up in Slovakia. Thanks to a very hard work, the first objectives were achieved on July 1, 1990 when the Ministry of Culture of the Slovak Republic signed the Document of Establishment and the Statute of the Slovak Caves Administration. The task of this administration is to ensure a good management of the show caves together with their suitable protection. In cooperation with UNESCO, a sort of Chart for the protection of the karst areas should be developed in order to acknowledge Karst as a natural heritage of Earth because Karst is one of the most important ecosystems. Show caves can play a relevant role in the development of these feelings in the public opinion.

Frumkin A, Ford Dc,
Rock salt is approximately 1000 times more soluble than limestone and thus displays high rates of geomorphic evolution. Cave stream channel profiles and downcutting rates were studied in the Mount Sedom salt diapir, Dead Sea rift valley, Israel. Although the area is very arid (mean annual rainfall approximate to 50 mm), the diapir contains extensive karst systems of Holocene age. In the standard cave profile a vertical shaft at the upstream end diverts water from a surface channel in anhydrite or elastic cap rocks into the subsurface route in the salt. Mass balance calculations in a sample cave passage yielded downcutting rates of 0.2 mm s(-1) during peak flood conditions, or about eight orders of magnitude higher than reported rates in any limestone cave streams. However, in the arid climate of Mount Sedom floods have a low recurrence interval with the consequence that long-term mean downcutting rates are lower: an average rate of 8.8 mm a(-1) was measured for the period 1986-1991 in the same sample passage. Quite independently, long-term mean rates of 6.2 mm a(-1) are deduced from C-14 ages of driftwood found in upper levels of 12 cave passages. These are at least three orders of magnitude higher than rates established for limestone caves. Salt cave passages develop in two main stages: (1) an early stage characterized by high downcutting rates into the rock salt bed, and steep passage gradients; (2) a mature stage characterized by lower downcutting rates, with establishment of a subhorizontal stream bed armoured with alluvial detritus. In this mature stage downcutting rates are controlled by the uplift rate of the Mount Sedom diapir and changes of the level of the Dead Sea. Passages may also aggrade. These fast-developing salt stream channels may serve as full-scale models for slower developing systems such as limestone canyons

Predicting natural cavities in chalk, 2001,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Edmonds Cn,
Introduction Chalk is a soluble carbonate rock with extensive karst development. Natural cavity occurrence initially appears to be random. In an area where the degree of influence of all cavity formational factors is similar, but dissolution is focused on one set of joints rather than another, then solution feature occurrence is perhaps random. This might be termed the microscale' view, measured at a scale of metres. However, if the pattern of natural cavity occurrence is considered at a macroscale' level, say measured in hundreds of metres or kilometres, then spatial patterns emerge suggesting dissolution is not as random as it might first appear. Spatial characteristics of natural cavity occurrence on the Chalk In order to analyse the spatial characteristics of natural cavity occurrence it was first necessary to collect as many records of solution feature occurrence as possible from published and unpublished sources including local authorities, Construction Industry Research and Information Association (CIRIA), Transport Research Laboratory (TRL), Building Research Establishment (BRE), National House Building Council (NHBC), the Environment Agency, water companies, and site investigation reports. Particular emphasis was placed on fieldwork to record new features revealed in a wide range of engineering works, road and motorway construction, and on visits to large numbers of working/disused chalk quarries and aggregate workings. A database of 2226 natural cavities was compiled, composed mainly of solution pipes, sinkholes (dolines) and swallow holes. The spatially related database (each cavity location being recorded by National Grid Reference) was carefully scrutinized to determine ...

Lunan "Shilin" (Stone Forest), human impact and protection of (eventual) World Heritage Site (Yunnan, China), 2001,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Kranjc Andrej, Liu Hong

The Chinese expression "shilin" (stone forest) is becoming an international term meaning megakarren, that is a Čforest« of intensively corroded limestone pinnacles. The best known is Shilin near the town of Lunan. The first known description of Shilin is from 1382. Shilin is very important tourist site. Modern tourism began to develop in 1980, in 1999 the number of visitors reached over 2 million. In 1981 the whole area (350 sq. km) was protected. Under the auspices of the National Ministry of Construction material is being collected for an application to inscribe Shilin into the list of World's Natural Heritage at UNESCO. Related to human impact the most important threats are: exploitation (destruction) of limestone pinnacles as a source of rock material; the pressure of population towards the protection zone due to their increase (need for new building plots); agriculture (farming and stockbreeding) connected to soil erosion and underground water pollution (use of fertilisers); fast growth of visitor numbers. The Shilin administration introduced different protection measures: ban on rock (limestone pinnacles) exploitation in the protection zone (orientation towards afforestation); construction of new tourist facilities out of the core zone (and demolition of some of them in that zone); establishment of a special protection department within Shilin management (18 person); education of "special voluntary rangers" - recruited among highly respected persons of villages and towns in the region.

Last glacial-Holocene paleoceanography of the Black Sea and Marmara Sea: stable isotopic, foraminiferal and coccolith evidence, 2002,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943

Multi-proxy data and radiocarbon dates from several key cores from the Black Sea and Marmara Sea document a complex paleoceanographic history for the last ~30[punctuation space]000 yr. The Marmara Sea was isolated from both the Black Sea and the Aegean Sea during glacial periods when global sea-level lowering subaerially exposed the shallow sills at the Straits of Bosphorus and Dardanelles (i.e. lake stage), and reconnected through both straits during interglacial periods, when rise of global sea level breached the shallow sills (i.e. gateway stage). Micropaleontological data show that during the `lake stage' the surface-water masses in both the Marmara Sea and Black Sea became notably brackish; however, during the `gateway stages' there was a low-salinity surface layer and normal marine water mass beneath. Two sapropel layers are identified in the Marmara Sea cores: sapropels M2 and M1 were deposited between ~29.5 and 23.5 ka, and ~10.5 and 6.0 ka, respectively. Micropaleontological and stable isotopic data show that the surface-water salinities were reduced considerably during the deposition of both sapropel layers M2 and M1, and calculation using planktonic foraminiferal transfer functions shows that sea-surface temperatures were notably lower during these intervals. The presence of fauna and flora with Black Sea affinities and the absence of Mediterranean fauna and flora in sapropels M1 and M2 strongly suggest that communication existed with the Black Sea during these times. A benthic foraminiferal oxygen index shows that the onset of suboxic conditions in the Marmara Sea rapidly followed the establishment of fully marine conditions at ~11-10.5 ka, and are attributed to Black Sea outflow into the Marmara Sea since 10.5 ka. These suboxic conditions have persisted to the present. The data discussed in this paper are completely at odds with the `Flood Hypothesis' of Ryan et al. (1997), and Ryan and Pitman (1999)

Late Quaternary history of the Marmara Sea and Black Sea from high-resolution seismic and gravity-core studies, 2002,

Hiscott R. N. , Aksu A. E. ,
Lithologic and multi-proxy paleoenvironmental data from 21 dated cores have been used to define three allostratigraphic units (allounits) within the late Quaternary successions of the Marmara Sea and Black Sea. Allounits are bounded by unconformities and their correlative conformities. In both regions, Allounit A extends from the seafloor downward to a ~12-11-ka sequence boundary, which is a major shelf-crossing unconformity in water depths less than ~100-110 m. In deep basins of the Marmara Sea, the lower part of Allounit A, designated Subunit A2, is a laminated sapropel, M1. On the shelf, Subunit A2 consists of backstepping delta lobes and early-transgressive barrier islands and sand sheets. Allounit B has only been recovered in Marmara Sea cores collected at water depths greater than ~90 m, and represents basinal or prodeltaic deposition during the 23-12-ka late Pleistocene lowstand. During the last glacial maximum, the shelves surrounding the Marmara Sea were subaerially exposed, and deltas of Allounit B accumulated along the present-day shelf edge. Following the post-glacial rise of global sea level to -75 m at ~12 ka, the Marmara Sea quickly became inundated and thereafter rose in synchroneity with the Mediterranean. By ~10 ka, the Black Sea rose to start spilling into the Marmara Sea, leading to establishment of a brackish-water lid that has persisted to the modern day. The strongest Black Sea outflow began at ~10 ka and persisted to ~6 ka, promoting the accumulation of sapropel M1 in the deep Marmara Sea, and progradation of an overflow delta just south of the exit from the Bosphorus Strait. Allounit C is a laminated sapropel (M2) in basinal cores, dated at ~30-23 ka. Like M1, it is believed that M2 accumulated during a period of increased brackish-water input into the Marmara Sea mainly from the Black Sea. In the Black Sea, wave erosion kept the shelf stripped of unconsolidated sediments during the falling sea level associated with the last glaciation and subsequent early stages of the post-glacial Holocene transgression. This erosion created a major unconformity, [alpha]. Shelf-edge deltas of Allounit B received their sediment during the last lowstand from small rivers that likely coalesced into a single system toward the shelf edge, at modern water depths of -100 to -110 m. These deltas were active until ~11-10.5 ka. Subsequently, sea level in the Black Sea rose to -40 m by ~10 ka, and a set of backstepping barrier islands developed on the shelf as part of the associated transgressive systems tract. Once water level reached -40 m, continued sea-level rise stalled until ~9 ka as the Black Sea began to spill across the Bosphorus Strait into the Marmara Sea

Reclamation of Limestone Quarries by Landform Simulation: Summary of Lessons Learnt from Trial Sites, 2002,

Landform simulation is the construction by restoration blasting of varied slope sequences on disused quarry faces consisting of rock screes, buttresses and headwalls which are selectively vegetated to produce landform/vegetation assemblages similar to those on natural limestone dales. This report presents a summary of monitoring of trial sites created at Hope and Tunstead Quarries. It assesses their success in terms of stability, vegetation establishment and visual appearance, and makes recommendations for the future application of the the technique.

Water quality modelling of Jadro spring, 2004,
Deprecated: Function get_magic_quotes_gpc() is deprecated in /home/isthin5/public_html/addon-domains/ on line 943
Margeta J. , Fistanic I. ,
Management of water quality in karst is a specific problem. Water generally moves very fast by infiltration processes but far more by concentrated flows through fissures and openings in karst. This enables the entire surface pollution to be transferred fast and without filtration into groundwater springs. A typical example is the Jadro spring. Changes in water quality at the spring are sudden, but short. Turbidity as a major water quality problem for the karst springs regularly exceeds allowable standards. Former practice in problem solving has been reduced to intensive water disinfection in periods of great turbidity without analyses of disinfection by-products risks for water users. The main prerequisite for water quality control and an optimization of water disinfection is the knowledge of raw water quality and nature of occurrence. The analysis of monitoring data and their functional relationship with hydrological parameters enables establishment of a stochastic model that will help obtain better information on turbidity in different periods of the year. Using the model a great number of average monthly and extreme daily values are generated. By statistical analyses of these data possibility of occurrence of high turbidity in certain months is obtained. This information can be used for designing expert system for water quality management of karst springs. Thus, the time series model becomes a valuable tool in management of drinking water quality of the Jadro spring

Change in perception of karst from morphology to morpho-hydrology:Turkish experience in comprehension of karst, 2004,

Ekmekci, Mehmet

Since its establishment as a science in the end of 19th century, methods applied in the study of karst evolved from classification to a system approach providing prediction in x,v,z and t. Information collected to answer the question "what is it" followed by the questions "why and how" and "what if". The change in questions required collection of new information which in turn changed perception of karst by related scientists. An overall evaluation of the progress in karst studies postulates an evolutionary character. Four major stages can be defined with transitional limits to track the change in perception of karst in accordance with the progress in the applied methodology. After discussing the history of karst studies in Turkey, the author questions the reason why the track did not progress parallel to the general evolution of karst studies in the world. Considering the fact that change in perception has caused shifts in meaning of the concepts and terms of karst, it is proposed to define terms not only on the basis of form but the processes of formation and function.
