  1. 1. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ebba Pegestam; [2022]
    Nyckelord :Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Sammanfattning : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

  3. 2. Site Application of a Channel Network Model for Groundwater Flow and Transport in Crystalline Rock

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jonas Pedersen; [2018]
    Nyckelord :channel network models; discrete fracture networks; model calibration; groundwater flow and transport;

    Sammanfattning : Groundwater flow and transport in deep crystalline rock is an important area of research. This is partly due to its relevance for constructing a long term repository for storing radioactive spent nuclear fuel in deep bedrock. LÄS MER

  4. 3. Grundvattenbildning till berg- En litteraturstudie samt fallstudie av järnvägstunneln delen Varberg-Hamra

    Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Sara Florén; [2015]
    Nyckelord :Groundwater recharge; tunneling; bedrock; Earth and Environmental Sciences;

    Sammanfattning : Both globally and from an individual perspective, water is the most important resource we have on earth. Knowledge of groundwater and groundwater recharge is important from many perspectives, such as environmental, socio-economic and structural engineering. LÄS MER

  5. 4. 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

  7. 5. Evaluation of methods for rock mass characterization and design of rock slopes in crystalline rock

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Johanna Gottlander; []
    Nyckelord :Geology; rock mechanics; rock slope stability in fractured crystalline rock; rock mass characterization and classification; rock slope design; slope failure;

    Sammanfattning : Construction of rock slopes is needed in many civil work projects. It is for example very common in road and railway cuts, but other applications include excavation for tunneling or building foundations, where perhaps sensitive constructions are present in the immediate vicinity.
