C. Sanz de Galdeano Instituto Andaluz de Ciencias de la Tierra (C.S.I.C., Universidad de Granada), Facultad de Ciencias, E-18071 Granada, Spain Abstract The analysis of the fractures in the marble forming sierras Blanca and Mijas (southern Spain), with faults of markedly different sizes and joints measured at 21 stations, demonstrate the presence of two principal directions of fractures (NNW-SS...

Karst aquifers are often classified as highly heterogeneous systems. Such systems are very complex to assess and model due to the presence of discontinuous porosity, large spatial variability of hydraulic parameters and the difficulties encountered in establishing the fundamental spatial properties of the system. In fact, karst aquifers have been studied and classified into groups based on seve...

Throughgoing fluid-conducting structures are the main elements of plumbing system sedimentary cover and play an important role in fluid migration, evolution basins lithogenesis, formation fluidogenic deposits (including hydrocarbons metals), use geothermal energy sources, risk assessment for geological depositories radioactive wastes, CO2 other materials. They widespread characterized by a vari...

Abstract The present study analyzes fractal dimensions for the daily discharge data series of 12 karstic springs registered over two decades in Northeast Hungary. Fluctuation observed is frequent and irregular, producing rough time series. level roughness measured by dimension defined different ways corresponds to intensity fluctuation. That, turn, results from structure aquifer, its conduits’ ...

Some previous studies have already highlighted the importance of Quaternary sediments as geoheritage, although related knowledge remains incomplete and geographically biased. Unique features are often overlooked in areas famous for their pre-Quaternary geoheritage. Moreover, established high-value linked to phenomena require comprehensive descriptions; therefore, it is reasonable analyze (even ...

The karst hydrological processes are the response of karst groundwater system to precipitation. This study provided a concept model of karst hydrological processes. The hydraulic response time of spring discharge to precipitation includes the time that precipitation penetrates through the vadose zone, and the subsequent groundwater pressure wave propagates to a spring outlet. Due to heterogenei...
