  1. 1. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Lindqvist; [2022]
    Keywords : Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Abstract : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. READ MORE

  3. 2. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lukas Rehn; [2021]
    Keywords : Boreal catchments; carbon cycling; carbon dioxide; DIC; headwater streams; Krycklan Catchment Study; trend analysis;

    Abstract : Inland waters are important systems for transforming, storing and transporting carbon along the aquatic continuum, but also by emitting carbon dioxide (CO2) and methane (CH4) to the atmosphere. In light of the last decades observed increase in dissolved organic carbon (DOC) in many inland waters across the northern hemisphere, a logical question arise whether other aquatic carbon species display similar trends.

  4. 3. Patterns and factors affecting brownification in a boreal river

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emil Winqvist; [2021]
    Keywords : Bolmen; brownification; precipitation; discharge; sulfur deposition; land use; trend analysis; Technology and Engineering;

    Abstract : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. READ MORE

  5. 4. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Iwan; [2021]
    Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE

  6. 5. Impact of different catchments on the Brownification of Lake Bolmen

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Kaela Chileshe; [2020]
    Keywords : Brownification; dissolved organic carbon DOC ; Iron Fe ; water colour; landscapes; climate change;

    Abstract : Increased DOC and Fe concentrations from terrestrial landscapes has led to the browning of boreal surface waters. The negative societal and ecological impacts of brownification are increased cost of water purification, increased presences of algae and cyanobacteria, loss of ecosystem services and reduced recreational value.
