  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. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Frida Agerberg; [2020]
    Nyckelord :Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Sammanfattning : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. LÄS MER

  4. 3. Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Björn Lönnerholm; [2006]
    Nyckelord :geohydrology; groundwater modeling; geostatistics; stochastic modeling; particle tracking; protection zones; glaciofluvial esker formation; tracer experiment;

    Sammanfattning : When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. LÄS MER

  5. 4. Ämnestransport med grundvatten i hydrogeologiska typmiljöer

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Björn Winnerstam; [2005]
    Nyckelord :Groundwater; geohydrology; hydrogeological type settings; contaminant transport; environmental impact; surface water; MSWI bottom ash.;

    Sammanfattning : Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater. LÄS MER

  7. 5. Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Joakim Riml; [2005]
    Nyckelord :geothermal heating; energy; geothermal heat pumps; geohydrology; GIS; groundwater; geology;

    Sammanfattning : The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge. LÄS MER
