  1. 1. Comparing Groundwater Drawdown with Estimated Influence Radius – A Case Study of Infrastructural Projects in Sweden

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

    Author : Staffan Druid; [2022]
    Keywords : Influence radius; analytical formula; groundwater lowering; sensitivity; Influensradie; analytisk beräkning; grundvattenavsänkning; känslighet;

    Abstract : Infrastructural projects may sometimes require excavation of soils and the groundwater table to be lowered, temporarily or permanently. As there are risks in connection to groundwater lowering, the extent of the affected area is of interest. READ MORE

  3. 2. Stochastic Settlement Model Including Creep Effects : Simulation of Groundwater Induced Subsidence

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Pierre Wikby; Ragnar Andersson; [2020]
    Keywords : creep settlement; secondary compression; geotechnical uncertainty; EMBANKCO; groundwater drawdown; time-dependent settlement model; krypsättningar; Sekundärkompression; geoteknisk osäkerhet; EMBANKCO; grundvattensänkning; tidsberoende sättningsmodell;

    Abstract : When underground openings are constructed, groundwater inflow can occur, which might lead to ground settlements, namely in clay. In these types of construction projects, it is beneficial to be able to quantify risks related to these settlements. A framework developed by Sundell et al. (2019, Risk Analysis, Vol. READ MORE

  4. 3. An Insight in the Mälarbanan Project : A Study of the Hydrological and Geotechnical Aspects of the Mälarbanan Project

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aksel Rahman; [2019]
    Keywords : settlement; groundwater; drawdown; soil; clay; CRS; sättningar; grundvatten; sänkning; jord; CRS; lera;

    Abstract : In “Mälarbananprojektet”, Trafikverket (The Swedish Transport Administration in Stockholm) want to expand the railway. Mälarbanan is at the present a railway that extends between Stockholm and Hovsta. READ MORE

  5. 4. Modeling contingency infiltration scenarios in MODFLOW : Stockholm Bypass and tunnel induced groundwater drawdown

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Aslan Abdo; [2019]
    Keywords : tunnel induced groundwater drawdown; MODFLOW; artificial recharge; land subsidence; grundvattenavsänkning; tunnel inläckage; MODFLOW; infiltration; sättning;

    Abstract : Subsurface constructions, such as tunnels, create hydrogeological challenges in mitigating risk of subsidence due to groundwater drawdown. Presenting readily made precautionary mitigation plans, such as strategically planned artificial recharge applications, can help effectivise the mitigation process. READ MORE

  6. 5. Investigating the decrease ofgroundwater levels and the effect of fracture zone on recovery time: A case study of decrease in groundwater levels in a tunnel construction site in Vinsta, Stockholm

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Evgenia Kassiou; [2017]
    Keywords : Groundwater; spatial analysis; Modified Double Mass Statistical Analysis; 3D model; COMSOL Multiphysics; fracture zone; recovery time; soil layer;

    Abstract : Groundwater is one of the main natural resources worldwide. Groundwater exists in aquifers below the earth surface and provides quantities of water for various purposes such as supply to households and businesses, public supply, drinking water supply, irrigation and agriculture. Sweden is also highly dependent on groundwater. READ MORE
