  1. 1. Effects of Forest Ditch Cleaning on Surface Water Quality

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

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

    Sammanfattning : 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. LÄS MER

  3. 2. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

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

    Författare :Henriette Nishimwe; [2023]
    Nyckelord :Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Sammanfattning : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. LÄS MER

  4. 3. Assessment of the Contribution of Groundwater Flow and Surface Flow from Bolmsö Island to Lake Bolmen, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Angelique Uwera; [2020]
    Nyckelord :Groundwater; Surface water; GMS-MODFLOW; Bolmsö Island; Lake Bolmen; Brownification.; Technology and Engineering;

    Sammanfattning : The increase of brownification in surface waters has been a problem for rivers and lakes from the northern hemisphere. The main factors of this water brownification are the increase of dissolved organic matter and iron in water bodies. LÄS MER

  5. 4. VERTICAL ELLIPTICAL ACCESS-SHAFTS Geometrical optimisation through FE-modelling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Björn Elfving; Aron Sandström; [2020]
    Nyckelord :Access-shafts; FE-modelling; Plaxis; Robot; Elliptical; Circular; Optimisation; Geotechnical; Engineering; Retaining; Structures; Tunnel; Soil; Interaction; Technology and Engineering;

    Sammanfattning : Urbanisation is causing densification of cities and more and more facilities are being placed in the underground to utilise the urban space as efficiently as possible. Access to the underground is obtained by constructing vertical access shafts. LÄS MER

  7. 5. Sorption of PFOS to different solid components as a function of aqueous chemistry

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Jean Noël UWAYEZU; [2018]
    Nyckelord :;

    Sammanfattning : Knowledge of fate and transport of chemical contaminants in the environment is essential for reducing their adverse effects to humans and wildlife. Surface and ground waters serve as drinking water which helps to sustain life. LÄS MER
