  1. 1. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Alireza Nickman; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

  2. 2. Geometrical controls on spectral induced polarization in time and frequency domain

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Sara Johansson; Lunds universitet.; Lund University.; [2019-03-05]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectral induced polarization; Microstructure; Electrical properties; Tomography; Multiscale;

    Abstract : What can we learn by transmitting electrical currents through electrodes in the ground? Geophysical methods can help us to locate the bedrock, valuable mineral ores, remains of ancient buildings and many other secrets hiding below the surface. However, it is not only the universal interest for the unknown that drives the geophysical research forward. READ MORE

  3. 3. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations

    University dissertation from Engineering Geology, Lund University

    Author : Roger Wisén; Lunds universitet.; Lund University.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; Hydrogeology; geographical and geological engineering; resistivity method; surface wave seismic method; inverse modelling; site investigation; geophysics;

    Abstract : Popular Abstract in Swedish Anpassningen av geofysiska metoder till infrastrukturtillämpningar är en viktig del i utvecklingen av geoteknisk förundersökningsmetodik. Det som här benämns geotekniska förundersökningar hänvisar till alla undersökningar som görs före eller under konstruktion, alltså sådana som syftar till att stödja och förbättra en konceptuell geologisk modell så väl som sådana som syftar till att ta fram en modell av geotekniska designparametrar.

  4. 4. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

    University dissertation from Engineering Geology, Lund University

    Author : Alfredo Mendoza; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; electrical resistivity; surface water; springs; Nicaragua; Hydrogeology; groundwater; teknisk geografi; geographical and geological engineering; Hydrogeologi;

    Abstract : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. READ MORE

  5. 5. Numerical modeling of coupled thermo-hydro-mechanical processes in geological porous media

    University dissertation from Stockholm : KTH

    Author : Fuguo Tong; KTH.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-hydro-mechanical processes; Porous geologicalmedia; Numerical modeling; FEM; Multiphase flow; Effective thermal conductivity; Water retention curve; Radioactive waste repositories; Bentonite; ; TECHNOLOGY Civil engineering and architecture Geoengineering and mining engineering Geoengineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Geoteknik och gruvteknik Geoteknik;

    Abstract : Coupled Thermo-Hydro-Mechanical (THM) behavior in geological porous media has been a subject of great interest in many geoengineering disciplines. Many attempts have been made to develop numerical prediction capabilities associated with topics such as the movement of pollutant plumes, gas injection, energy storage, geothermal energy extraction, and safety assessment of repositories for radioactive waste and spent nuclear fuel.
