The call for papers for the international karst conference “Karst without Boundaries” is now out. This conference is organized within the UNESCO’s DIKTAS project framework and will be held in June 2014 in the lands of spectacular classic Dinaric karst.
The National Speleological Society (NSS) of the USA is moving its headquarters and you benefit!
This special issue will be dedicated to geoparks and other approaches for territorial management and tourism in karst areas - Call for Papers
The British Cave Research Association is proud to announce the publication of its new book, Caves and Karst of the Yorkshire Dales (Volume 1)
A book about the use of karst and caves during wars and other conflicts.

One of the principal aims of hydrogeology is to propose a reasonably adequate reconstruction of the groundwater flow field, in space and in time, for a given aquifer. For example, interpretation of the chemical and isotopic composition of groundwater, understanding of the geothermal conditions (anomalies) or forecasting the possible effects of industrial waste disposals and of intensive exploitation nearly always would require the knowledge of the regional and/or local groundwater flow systems such as defined by Toth (1963). The problem of estimating the groundwater flow field in fractured and karstified aquifers is approached within the framework of a conceptual diagram showing the relationship between groundwater flow, hydraulic parameters (aquifer properties and boundary conditions), distribution of voids and geological factors.
Autoregulation between groundwater flow and karst aquifer properties, duality of karst, nested model of geological discontinuities, scale effect on hydraulic parameters and use of numerical finite element models to check the interpretation of the global response of karst springs are some of the subjects addressed by the author. Inferences on groundwater flow regime with respect to the stage of karst evolution can be made only if the hydraulic parameter fields and the boundary conditions are known by direct observations, or estimated by indirect methods for the different types of karst. Practical considerations on the monitoring strategies applied for karst aquifers, and on the interpretation of the global response obtained at karst springs will complete the paper, which throughout reflects the point of view of a hydrogeologist.
