Recherches nouvelles sur les karsts des gypses et des vaporites associes ; seconde partie : gomorphologie, hydrologie et impact anthropique, 1993, Nicod, J.
Surface features reflect not only the importance of cave collapse, but also the action of present and inherited zonal processes. The rates of geomorphological evolution are compared (main data in table 1). The particularities of hydrological flow are studied, as well as the dynamic of some karstic lakes, particularly the Banyoles Lake (Catalonia). The various processes generate numerous hazards enumerated in the paper and evident in urban and suburban areas and in the civil engineering works such as tunnels, dams, etc.

Living with the lake, living without the lake An introduction into the research of the way of life by the intermittent karstic lakes Petelinjsko jezero and Pal¹ko jezero, 2005, Erjavec M. , Perš, Ič, M.

People of Petelinje and Palčje have adapted to the ever-changing nature of the intermittent karstic lakes through the centuries. Both lakes are filled with water only a part of the year, so that the grassy areas usually provide a yearly arvest of hay. Palško jezero and the shores of Petelinjsko jezero are suitable for pasturing. Economically the lakes were and still are connected with raising livestock. Agriculture is now no longer profitable, so the only way to preserve the land is by the state devoting enough money for agriculture. The lake was connected to another economic activity until the middle of the 20th century, ice making. Additional supplementary activities dependent on the lake are hunting and gathering. Petelinje and Palčje villagers had to share their lakes with the Austro-Hungarian, Italian and Yugoslav armies in the past; they left traces that can still be seen today. The lakes, with their unusual and highly picturesque nature, represent a place of peace and relaxation to the locals.


Influence of meteorological variables to water quality in five lakes over the Aggtelek (Hungary) and Slovak karst regions – a case study, 2013, Samu Andrea, Csépe Zoltán, Báránykevei Ilona

The main objective of this study is to analyse the effect of tendencies in the meteorological variables on the water quality on the example of five lakes in the Aggtelek and Slovak karst. The data set used eleven water quality parameters (oxygen saturation, chemical oxygen demand, nitrate, nitrite, orthophosphate, total phosphorus, ammonium, pH, conductivity, iron, manganese), as well as daily data of six climatic parameters from the period 2008­2010. A cluster analysis is performed in order to determine the climate impact on the water quality parameters. Furthermore, factor analysis with special transformation, as a novelty in the study, is implemented to find out the weight of the climate parameters as explanatory variables and hence their rank of importance in forming the given water quality parameter as an influencing variable. The study introduces a methodology for analysing the climate impact on the water quality parameters. In order to reduce the number of the water quality parameters, a so called two­stage factor analysis was performed, which is a novel procedure. Application of the two­stage factor analysis involves both benefits and disadvantages. Its benefit is that it substantially reduces the number of resultant variables. In this way, information loss of the retained factors is around 20%. As a result, we received that both positive and negative extreme values of water quality parameters can be associated with weak or breaking­up warm fronts passing through over the region. On the contrary, the role of anticyclones or anticyclone ridge weather situations is supposed to be irrelevant. Unstable and extreme weather conditions act in the direction of breaking up the balance that would support the good water quality. This process does not benefit the water use nor the sensitive karst hydrogeological system
