Zur hydrologischen Rayonierung und Grundwassernutzung in Afghanistan. (Hydrogeologicalregionalization and ground-water utilization in Afghanistan)
On the base of the hydrometeorological hydrographical situation, a regionalhydrogeological general view on Afghanistan is given. Three regions are characterized with regard to the hydrogeology (Superior Amu-Daria basin, South Afghan artesian basin
, Indus region). The contribution ends with hints at aspects of ground-water utilization.
Outline of the hydrogeology of the Cimino and Vico Volcanic area and of the interaction between groundwater and Lake Vico (Lazio region, Central Italy)
Groundwater ; Hydrogeology ; Italy ; Lake ; Lazio ; Water resources
The study area covers the Cimini and Vico volcanic complexes in the province of Viterbo (Northen Lazio Region, Italy), where a large-scale exploitation of the water resources co-exists with fragile environmental conditions. The main aim of the study
was to improve our knowledge of the hydrogeological setting of the system in order to quantify the groundwater resource and to examine the interaction between the groundwater and lake Vico in their specific geological framework. - (NF)
A new hydrogeological map of Guelderland and Flevoland
A new mapping technique is proposed to represent on sheet the hydrogeological date of a region. The map has been composed for the situation of The Netherlands but can most likely be used for any area, where the aquifer systems consist
Tectonic speleogenesis of Devis Hole, Nevada, and implications for hydrogeology and the development of long, continuous paleoenvironmental records

Devils Hole is located in a region of active extension. Such extensional environments can provide conditions favorable for accumulation of deposits preserving long, continuous paleoenvironmental records. The precipitates in Devils Hole store
limestones. Morpholoical features and hydrogeological conditions suggest that sapping processes were responsible for the development of the valley network. Furthermore, the particular hydrogeological conditions of the region along with the Pleistocene glacio
The central area of the Apulia region is characterized by a network of valleys with peculiar features, locally called gravine or lame. They are short, straight valleys, deeply incised in Plio-Pleistocene calcareous sandstones and in Mesozoic
Waste disposal sites are an important aspect of regional planning. The Laboratory of Applied Geology and Hydrogeology (State University Ghent) studied several cases concerning the planning or cleanup of waste disposal sites in Flanders. Mathematical
modeling reveals the importance of a proper knowledge of stratification and hydrogeological characteristics of the surroundings of waste disposal sites.
The purpose of the study is to reveal how terrestrial impact structures can modify regional morphology, geology and hydrogeography-hydrogeology of the surface, as well as how impact structures assist the characterization of surface features

The area in the northern foreground of the W-Mecsek is rich in landslide processes. The types are described with their hydrogeological and relief background. (DLO).
The well known sulphureous springs are reported both in regional and national geological maps, but detailed studies have been rarely carried out. In this paper the AA. describe the sulphureous waters on the basis of the hydrochemical facies
How the Quaternary climatic change affects present hydrogeological system on the Chinese Loess Plateau : A case study into vertical variation of permeability of the loess–palaeosol sequence

In addition to the analysis of the hydrogeological significance of the formations in the surroundings of Aggtelek, the A. intends to present a comprehensive view on the probable flow directions of the underground waters, their spatial distribution
The dominant role of relief is emphasized in the explanation of the regional distribution of salt-affected soils. The interactions between morphological, lithological and hydrogeological factors are very close. With the climatic conditions
