  1. 11. Hydrological assessment and water management study in Norra Bunn With a focus on fish stock conservation

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Qianqian Li; [2021]
    Nyckelord :hydrological assessment; fish stocks conservation; Norra Bunn; water management; HYPE; Technology and Engineering;

    Sammanfattning : Fokus för denna studie är att undersöka statusen för Norra Bunnsjön och de utmaningar den står inför idag med betoning på vattenresurshantering för ett bättre bevarande av fiskbestånden. För att uppnå målen genomfördes litteraturgranskningar, datainsamling från olika källor och vattenprovtagningar på plats. LÄS MER

  3. 12. Spruce Forests and Peat Wetlands in Lake Bolmen’s Catchment Both Leak and Degrade Coloured Dissolved Organic Carbon

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Jasmin Borgert; [2021]
    Nyckelord :Brownification; land use; DOC; iron; water colour;

    Sammanfattning : Lake browning in the northern hemisphere is endangering crucial ecosystem services. Darker water decreases fish and primary production as well as touristic and recreational values. It furthermore requires intensive treatment to receive safe drinking water. Brownification is connected to iron and coloured dissolved organic carbon (DOC). LÄS MER

  4. 13. Assessment of Groundwater Flow to Lake Bolmen

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

    Författare :Massimiliano Favaro; [2021]
    Nyckelord :Groundwater; modelling; MODFLOW; GMS; hydrogeology; Technology and Engineering;

    Sammanfattning : This work reports the research and findings concerning the processes of groundwater flow and distribution to lake Bolmen in the Småland region, Sweden. The watershed of Bolmen is of high interest since it provides water for drinking and energy purposes, representing a resource of notable importance for the society of southern Sweden. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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. LÄS MER

  7. 15. Modelling of water and material transport in River Storån to Lake Bolmen

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Imjal Sukupayo; [2021]
    Nyckelord :Brownification; Water Color; Dissolved Organic Matter; Discharge; hydraulic analysis; Tracer Analysis; Dispersion coefficient; Advection and Diffusion; Bolmen Lake; Storån River; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. LÄS MER
