  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. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jakob Andrén; [2021]
    Keywords : hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Abstract : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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. READ MORE

  5. 4. River-Aquifer Interaction in the Uppsala Esker - a Modelling Study of a Proposed Drinking Water Production site

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

    Author : Kalle Kjellander; [2018]
    Keywords : Surface water-groundwater interactions; MODFLOW-model; Numerical model; Induced infiltration; Hydraulic conductivity; Grund- och ytvattenutbyte; MODFLOW-modell; numerisk modell; inducerad infiltration; hydraulisk konduktivitet;

    Abstract : The Swedish municipalities of Gävle and Älvkarleby need new sources of drinking water as the population grows. Gästrike vatten AB has employed the consultant firm Midvatten AB to assess the possibility of a new groundwater extraction site on the Uppsala esker between Älvkarleby and Skutskär in northern Uppland county.

  6. 5. Fines Content and Density Effects on Tailings Behaviour : A Laboratory Study on Geotechnical Properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Viktor Wiklund; [2018]
    Keywords : strength; compressibility; permeability; anrikningssand; hållfasthet; konsolidering; permeabilitet;

    Abstract : Tailings are a rest product from the extraction of metals and minerals, and is therefore produced in large volumes by all mining companies. One common way to store tailings material is to deposit it as a hydraulic slurry on a tailings impoundment, where the tailings are held in place by tailings dams. READ MORE
