  1. 1. Groundwater-Seawater Interactions : Seawater Intrusion, Submarine Groundwater Discharge and Temporal Variability and Randomness Effects

    Författare :Carmen Prieto; Georgia Destouni; Vassilios Kaleris; KTH; []

    Sammanfattning : Fresh groundwater quality and availability in coastal areas is affected by seawater intrusion into coastal aquifers, and coastal water quality and ecosystem status may be significantly affected by groundwater pollutants that are transported into coastal waters by submarine groundwater dis-charge (SGD). This thesis uses an overall regional perspective for investigating: i) seawater intru-sion and its possible control in sustainable coastal groundwater management; ii) SGD and its relevant quantification as one interacting part among the diverse main regional pathways of freshwater and tracer/pollutant inputs from land to sea; and iii) the integrated system functioning of both i) and ii) as main components of the same coastal groundwater system.

  3. 2. The mobility of natural uranium at Forsmark, Sweden, through geologic time

    Författare :Lindsay Krall; Carl-Magnus Mörth; David Read; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uranium; radium; mineralogy; geochronology; submarine groundwater discharge; spent nuclear fuel; geochemical modelling; Geology; geologi;

    Sammanfattning : In this thesis, the response of uranium minerals and poorly crystalline phases to changes in geochemical conditions through geological time has been assessed in order to understand the mobility of natural uranium in the fracture network of a proposed site for a spent nuclear fuel repository in Forsmark, Sweden. Identification and characterization of solid phase uranium have been performed through electron microprobe analysis and optical petrography (Article I). LÄS MER

  4. 3. Modelling water and solute flows at land-sea and land-atmosphere interfaces under data limitations

    Författare :Yoshihiro Shibuo; Georgia Destouni; Jerker Jarsjö; Clifford Voss; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Submarine groundwater discharge; unmonitored flows; catchment hydrology; evapotranspiration; bathymetry; GIS; Aral Sea; nuclear waste repository sites; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Sammanfattning : Water and vapour flows from land to sea and the atmosphere are important for water resources, coastal ecosystems and climate. This thesis investigates possible methods for modelling these flows under often encountered unmonitored hydrological conditions and data limitations. LÄS MER
