hipogenic caves in the region of Murcia-Spain Vol.I
First publication of three volumes devoted to hipogenic caves in the region of Murcia - Spain Most of the wells in this region of southwestern Spain are hypogene origin, in this first volume eight holes are analyzed in their hypogean aspects; networks, morphologies and speleothems, which are common in the caves of Murcia The hipogenic characteristics that are common to each of the wells tested, this table can be used for other cavities helping to recognize the common elements and features of the hipogenic caves are presented in a table in Spanish online http://issuucom/aros-andres/docs/cuevas-hipogenicas-murcia-i. ...

Karstification and Groundwater Flow
Abstract:

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.
