    Abstract : The project is part of a larger investigation of the water protection area Donauried-Hürbe. This area is a recharge zone used by one of Germany’s biggest water supply companies, the Zweckverband Landwasserversorgung (LW). READ MORE

  3. 37. Artificial Groundwater Injection : A Study of Groundwater Level Control in Swedish Infrastructure Projects

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Martin Kjellberg Skjenken; [2019]
    Keywords : Groundwater; Subsidence; Artificial Recharge; Artificial Groundwater injection; Climate Change; Numerical modelling; Infrastructure and Swedish Transport Administration; Grundvatten; marksättningar; Skyddsinfiltration; Framtida klimatförändringar; Infrastruktur; Numerisk modellering; Trafikverket;

    Abstract : This thesis sets out to increase the knowledge of artificial groundwater injection (AGWI) in Sweden on behalf of the Swedish Transport Administration. This has been done by firstly conducting a literature review which provided the background which comprises mainly groundwater theory and subsidence. READ MORE

  4. 38. Flow Paths in the Húsmúli Reinjection Zone, Iceland

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Sigrún Tómasdóttir; [2018]
    Keywords : Húsmúli; Hellisheiði Power Plant; geothermal reinjection; tracer tests; numerical modeling; Húsmúli; Hellisheiði kraftverk; geotermisk injektion; spårtest; numerisk modellering;

    Abstract : Reinjection of spent geothermal fluids has become common practise in geothermal power plants. Reinjection can, despite being mostly beneficial, have unwanted effects such as cooling of nearby production wells and injection-induced earthquakes. READ MORE

  5. 39. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Haoyu Wei; [2018]
    Keywords : Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. READ MORE

  6. 40. Effects and Models of Water Injection in an SI Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Joel Westling; Haris Subasic; [2018]
    Keywords : ;

    Abstract : Downsizing and turbocharging is a popular combination nowadays in cars inorder to decrease the fuel consumption. However, the boost pressure increasesthe risk of engine knock, limiting the engine in high-load operating points. Inthe current engines, fuel is used to cool the engine in these operating points,leading to a higher fuel consumption. READ MORE
