1. 11. Structural model of the Lambarfjärden area from surface and subsurface data in connection with the E4 Stockholm bypass

   University essay from Berggrundsgeologi

   Author : Anna Vass; [2012]
   Keywords : Lambarfjärden; sturctural model; fracture; E4 Stockholm Bypass;

   Abstract : The present Master thesis is written in connection with the E4 Stockholm bypass, which is a future motorway linking northern and southern Stockholm, and will mostly run through tunnels. The bypass will cross the Lake Mälaren in the Lambarfjärden area, where a fault is indicated on the geological maps, which would create risks for tunneling. READ MORE

3. 12. Remote Sensing and Statistical Analysis of Fracture Populations Around Lake Thingvallavatn, SW Iceland

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Johan Oxenstierna; [2012]
   Keywords : ;

   Abstract : This study aims at a description and statistical analysis of tectonic and magmatic fractures in the Western Volcanic Zone (WVZ) on Iceland. Two fracture populations are studied with respect to their distance to the Hengill volcano: The southern area is between 0-10 kilometers from the volcano and the northern area is between 16-25 kilometers from the volcano.

4. 13. Groundwater resources in coastal hard rock terrains : Geostatistical and GIS approach

   University essay from KTH/Mark- och vattenteknik

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

   Abstract : 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. READ MORE

5. 14. Modelling and visualisation of geological structures in the Tunberget tunnele

   University essay from KTH/Geodesi och satellitpositionering

   Author : Anwar Negash Surur; [2008]
   Keywords : ;

   Abstract : 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. READ MORE
