  1. 1. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Osterman; [2023]
    Keywords : Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Abstract : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. READ MORE

  3. 2. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Magnusson Petter; [2023]
    Keywords : Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Abstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

  4. 3. The Influence of Infiltration Capacity and Antecedent Soil Moisture Conditions on Urban Pluvial Flooding

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

    Author : Disa Barkefors; [2023]
    Keywords : Urban pluvial flood; 2D modelling; MIKE ; urban green area; soil moisture; Chicago Design Storm;

    Abstract : Urban pluvial floods occur during extreme rain events and both occurrence and magnitude of these floods are expected to increase. Preserving or constructing green areas in urban areas has been shown to mitigate and control these floods. READ MORE

  5. 4. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Adnan Asif Rifat; [2023]
    Keywords : Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Abstract : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. READ MORE

  6. 5. 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
