  1. 16. Groundwater resources in coastal hard rock terrains : Geostatistical and GIS approach

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :S. Emad Dehkordi; [2009]
    Nyckelord :Fractured hard rock; Multivariate statistics; GIS; Groundwater potential; Lineament; Salinity;

    Sammanfattning : Stockholm archipelago is a combination of coastal and young glaciated conditions on hard rock geology with almost no primary porosity and very limited secondary porosity. Therefore the aquifer is both of limited capacity and exposed to salinity problem. In this context importance of fractures and soil cover is magnified. LÄS MER

  3. 17. Modelling and visualisation of geological structures in the Tunberget tunnele

    Master-uppsats, KTH/Geodesi och satellitpositionering

    Författare :Anwar Negash Surur; [2008]
    Nyckelord :;

    Sammanfattning : The 3-d visualisation of a section of the Tunberget tunnel and important fracture zones was accomplished by combination of the topographic surface, measurements at the surface of fracture planes together with surfaces of dolerite dykes, results from magnetic modeling of dolerite dykes and tunnel mapping data. The topographic surface was represented as elevation contours with 1 m equidistance. LÄS MER

  5. 19. Water supply study at Manama, southern Zimbabwe

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Patrich Holmström; Per Möller; Mats Svensson; [1991]
    Nyckelord :Zimbabwe; groundwater; geology; geography; VLF; slingram; resistivity; sand dam; Earth and Environmental Sciences;

    Sammanfattning : This paper describes a groundwater prospecting project, including two parts, in the rural area in southern Zimbabwe. The first part deals with a gelogical survey and locating of waterbearing fracture zones with the electromagnetic methods Slingram and VLF, and a resistivity instrument. LÄS MER
