Une morphologie karstique typique en zone intertropicale : les karsts du Bas Zare, 1985, Quinif, Y.
A TYPICAL MORPHOLOGY OF TROPICAL KARSTS: THE KWILU BASIN IN THE LOWER-ZAIRE - The Kwilu basin, in the region of Bas-Zaire, shows typical landscapes of tropical karsts: cone and tower karsts shaped in precambrian limestones of the "Groupe schisto-calcaire". These precambrian series are little tectonised. They are covered with cenozoic formations which are important in the evolution of the karst. Different types of cavities are studied and replaced in the morphostructural context: old caves, originating in phreatic zone and now cut by the erosion, river streams in tunnel-caves, network under the water table. The superficial forms are interpreted as successive evolutive steps: dissection of a surface (morphological or structural) by a dendritic hydrographic network, birth of a cone-karst being transformed in tower-karst overlooking a new surface. We insist on the morphogenetic importance of the paleoclimatic changes and on the existence of an intertropical karstic morphology in stable craton.

Le karst des Monts Padurea Craiulu (Roumanie), 1986, Badescu, D.
THE KARST OF PADUREA CRAIULUI MOUNTAINS AND THE SYSTEM OF TINOASA-CIUR-TOPLITZA DE ROSIA (ROMANIA) - Padurea Craiului mountains represent one of the most interesting karstic area of Romania. The existence of limestones affected by a lot of tectonics accidents had done these mountains to have distinct morphological aspects. The relative developed hydrographic network, together with the geological structure and the favourable tectonic, brought about a lot of endokarstic and exokarstic phenomena too. This is very clear in Runcuri plateau, which lodges the karstic systems Tinoasa-Ciur-Toplitza. The influence of the tectonic is demonstrated by the underground observations about the fissures. The development of these systems, as well as the morphology of the caves, are influenced by the structure and texture of the different jurassic limestones.

Prsentation splologique du massif des Fanges-Roc-Paradet (Aude/Pyrnes orientales), 1987, Ournie, B.
SPELEOLOGY OF THE FANGES-ROC PARADET MOUNTAIN KARST (AUDE /EASTERN PYRENEES, FRANCE) - The Fanges-Roc Paradet Mountain karst (S = 40 km2) contains a large underground cave, the " Cthulhu Dmoniaque-Puits de lEngoulevent " system (L = 13km, D = -302m). This region of Fenouilldes is characterized by a mediterranean climate and presents different surface karst features (pavements, depressions, dry valleys). Synthesis data are given in hydrogeology and speleology. The complexity of subterranean drainage and caves can be explained by an old karstification begun during the mio-pliocene uplift, from an eogene peneplain. The association Arkham co-ordinates the researches and prepares some publications.

Regional scale transport in a karst aquifer, 1. Component separation of spring flow hydrographs, 1989, Dreiss S. J.

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

Morphometric analysis of dolines, 1992, Bondesan Aldino, Meneghel Mirco, Sauro Ugo
The doline is the most specific surface form of karst landscapes, which enables one to distinguish them from "normal" erosion landscapes shaped by surface water. From a morphodynamic point of view the doline constitutes an elementary hydrographic unit, comparable to a simple basin, which, with its system of slopes, conveys water to the absorbing points at the bottom into an underground network. The morphometric study of these karst landforms enables a quantitative analysis of karst environment. Comparisons of the various parameters may give unexpected results and lead to new hypotheses about the evolution and the dynamism of the karst "geo-ecosystem". All the main morphometric parameters of the dolines are listed and explained and a preliminary discussion about some methods of spatial analysis is developed. It is intended to give methodological suggestions about data sources, systems of measurement, and to stimulate some reflection on the choices of possible processing of morphometric variables and on the significance of statistical analysis applied to different parameters. After a brief review of some morphometric and spatial analyses made in the past by different authors, three different examples are presented, relative to karst areas of the Venetian Prealps (Cansiglio-Cavallo, Montello) and of the Carso di Trieste. From these few examples one can understand how to confront this complex subject and what kind of results the analysis of morphometric parameters may give. In interpreting the results it is evident that one must not forget the geological, geomorphological, pedological, vegetational and climatic context of the karst area.

By analysing the hydrographs of karst springs it is possible to identify aquifer characteristics and, accordingly, the main features of a karst rock-fissure massif. Consequently, relevant data can be obtained by analysing hydrograph recession curves. This paper presents a detailed analysis and explanation of numerous cases of break points on recession curves via various values of the recession coefficient alpha in Maillet's (1905) equation. The paper also identifies the relationship between alpha and a linear reservoir coefficient by employing groundwater hydrograph methods. It is shown that the linear reservoir coefficient changes with time in accordance with changes of the flow conditions in the karst massif

The exploitation and development of the ''Grotta di Bossea'' as a show cave, 1994, Fisanotti Giorgio, Peano Guido
The Bossea Cave has a great interest from the point of view of nature and the environment because many karst and speleogenetic processes are still active. The water stream flowing in the cave was the determining factor of some picturesque morphologies and splendid scenographic effects. An underground laboratory for experimental researches (the "Bossea Scientific Station") was established in the cave and is operating since 1969 (Biological Section) and 1982 (Physical Section). The cave has been explored and studied since 1850 and opened to the public in 1874. At present its exploitation can be furtherly emphasized. For this purpose a programme was prepared according the following items: 1; rearrangement of the tourist facilities 2; best exploitation of internal hydrography 3; creation of alternative trails 4; improvement of the scientific facilities 5; creation of new outside facilities 6; preparation of literature and visual aids. The goals of the Scientific Station installed inside the cave and the results achieved are described by Guido Peano, laboratory director; the cave exploitation project, concerning both the scientific and tourist facilities, is due to Giorgio Fisanotti.

Evaluation of recession hydrographs, from four karst springs in Europe, provides important information concerning the flow process operating in karst aquifer systems. Three analytic equations are used to evaluate the hydrographs: Mangin's equation, that assumes the recession is composed of both quickflow and baseflow; Coutagne's equation which considers the recession to be the response of a single reservoir; and a new function, H(t) (which is derived from Coutagne's equation), that refers to the whole recession curve. Using Mangin's equation it is apparent that the saturated zone and thus baseflow exerts nearly complete control over the discharge of La Villa spring and is fairly important at Fuente Mayor and Baget springs, but is much less significant at Aliou spring. The saturated zone accounts for 100%, 90%, 91%, and 40% respectively for these springs. Using Coutagne's equation and H(t) it is concluded that for Aliou and Baget springs, water flows freely in the high transmissive zones, but in the poorly transmissive zones, there is little continuity of connection in the system. At Fuente Mayor spring the differences in these zones are not so apparent and a gradual transition occurs. However, at La Villa spring, the karst aquifer is evidently much more homogeneous and the discharge is similar to that of a porous intergranular aquifer

Analysis of well hydrographs in a karst aquifer: Estimates of specific yields and continuum transmissivities, 1996, Shevenell L. ,
Hydrograph analysis techniques have been well developed for hydrographs obtained from streams and springs, where data are cast in terms of total discharge. The data obtained from well hydrographs provide water level versus time; hence, a method of hydrograph analysis is required for situations in which only water level data are available. It is assumed here that three segments on a recession curve from wells in a karst aquifer represent drainage from three types of storage: conduit (C), fracture (F) and matrix (M). Hydrographs from several wells in a karst aquifer are used to estimate the specific yields (S-y) associated with each portion of the aquifer (C, F, M), as well as continuum transmissivities (T). Data from three short injection tests at one well indicate continuum rat this well bore is approximately 5 m(2) day(-1), and tests at numerous other wells in the aquifer yield results between 1 and 7 m(2) day(-1). The T estimated with well hydrographs from two storms indicates a T of 9.8 m(2) day(-1). Well-developed conduit systems in which water levels in wells show a flashy response typically show S(y)s of 1 x 10(-4), 1 x 10(-3), and 3 x 10(-3) for C, F, and M, respectively. Less well-developed conduit areas show more nearly equal S(y)s (8.6 x 10(-4), 1.3 x 10(-3), 3 x 10(-3)). Areas with no evidence for the presence of conduits have only one, or in some cases two, slopes on the recession curve. In these cases, water-level responses are slow. Recession curves with a single slope represent drainage from only the lower T matrix. Those with two slopes have an additional, more rapid response segment on the recession curve which represents drainage from the higher T, lower S-y, fractures in the system
