  1. 1. Modelling the Water Table in a Bog

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Bowley; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. Effects of Forest Ditch Cleaning on Surface Water Quality

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Emeli Arvidsson; [2023]
    Keywords : Ditch cleaning; forest clear-cut; water quality; water chemistry;

    Abstract : Ditch cleaning (DC) is recommended by authorities to Swedish landowners to maintain forest productivity after forest harvest by lowering groundwater tables of catchment soils. Knowledge regarding the impact of this practice on surface water quality is limited, and results from previous research vary. READ MORE

  4. 3. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

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

    Author : Daniel Estmark; [2022]
    Keywords : Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

    Abstract : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

  5. 4. 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

  6. 5. Groundwater Inflow into Fractured Rock Tunnels

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mariam Beydoun; [2022]
    Keywords : groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Abstract : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. READ MORE
