  1. 1. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sandra Edström; [2022]
    Keywords : groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

    Abstract : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

    Keywords : Single borehole dilution tests SBDT ; Darcy flow velocity; karst aquifer; porous aquifer; Donauried-Hürbe; Germany; Technology and Engineering;

    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

  5. 4. Mass conservative network model for convective net flow in a complex urban geometry

    University essay from Umeå universitet/Institutionen för fysik

    Author : Linus Olofsson; [2016]
    Keywords : Network model; Street canyons; Intersections; Urban dispersion; CFD data; CFD simulations; Atmospheric exchange;

    Abstract : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. READ MORE
