  1. 1. 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

  3. 2. 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.

  4. 3. 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

  5. 4. Investigation of sustainable methods to reduce water hardness in drinking water treatment plants

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Élise Karlsson Faudot; [2021]
    Keywords : Water hardness; sustainability; Bulltofta water treatment plant; water hardness reduction; plant biomass; plastic; pumice stone; adsorption; Earth and Environmental Sciences;

    Abstract : Water hardness is caused by magnesium and calcium ions (Mg2+ and Ca2+), and can result in formation of deposits, destruction of soap and increase of copper corrosion in old plumbing pipes. To soften the originally hard groundwater supplying 20% of Malmö’s drinking water, Bulltofta water treatment plant imports burned lime from Germany. READ MORE

  6. 5. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Mikaela Casselgård; [2020]
    Keywords : ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Abstract : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. READ MORE
