  1. 1. The Impact of Boundary Condition on Groundwater Flow : Topography v/s Recharge Controlled

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Harshitha Sridhar; [2020]
    Nyckelord :Regional Groundwater flow; topography boundary condition; recharge boundary condition; 3D numerical modelling; groundwater flux profile; Regionalt grundvattenflöde; topografi gränsvillkor; laddningsgränsvillkor; numerisk 3D-modellering; grundvattenflödesprofil;

    Sammanfattning : Groundwater interactions at a regional scale are of great importance to characterize subsurface flow processes. Extensive researches have been conducted previously to determine the main factors controlling the regional implications on groundwater flux circulation. LÄS MER

  3. 2. Lithospheric-Scale Stresses and Shear Localization Induced by Density-Driven Instabilities

    Master-uppsats, Geofysik

    Författare :Christiane Heinicke; [2010]
    Nyckelord :Lithosphere; localization; numerical modeling; shear heating; stress; subduction initiation;

    Sammanfattning : The initiation of subduction requires the formation of lithospheric plates which mostly deform at their edges. Shear heating is a possible candidate for producing such localized deformation. In this thesis we employ a 2D model of the mantle with a visco-elasto-plastic rheology and enabled shear heating.
