  1. 1. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden

    M1-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Edevardt Johan Danielsen; Alexandra Jonsson Valderrama; [2022]
    Nyckelord :Hydropower; Reservoir; Freshwater; automated Flux chambers; Emissions; Ebullition; Diffusion; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Dissolved oxygen; DO; Variability; Spatial; Temporal; Dissolved inorganic carbon.; Vattenkraft; Reservoar; Sötvatten; automatiserade Fluxkammare; Utsläpp; Ebullition; Diffusion; Växthusgaser; GHHs; Metan; CH4; Koldioxid; CO2; Löst syre; DO; Variabilitet; Rumslig; Temporal; Löst oorganiskt kol.;

    Sammanfattning : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

  3. 2. Estimating greenhouse gas emission via degassing and modeling temperature profiles in tropical reservoirs.

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Johan Wilson; [2020]
    Nyckelord :Metan; Vaxthusgaser; Vattenkraft; Klimat;

    Sammanfattning : The aim of this project was to quantify the greenhouse gas (GHG) emissions from the degassing process ofhydroelectrical reservoirs in tropical regions.Reservoirs represent 25 % of the total area of man-made freshwater systems and are a source of GHG emissions tothe atmosphere.

  4. 3. Hydrological Modelling of Al Auja Earth Dam in the Lower Jordan Valley.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Otto Rimfors; Vadim Velichkin; [2015]
    Nyckelord :Hydrological modelling; arid areas; Jordan Valley; water scarcity; Al Auja; HEC-HMS; SMA; CN;

    Sammanfattning : In a populated region with very high potential evapotranspiration, where the rainwater falls only during the winter and mostly in the mountains, the need for sustainable water management and fair distribution is crucial. In the West Bank, Palestine, the main potable water source is a karst mountain aquifer system. LÄS MER

  5. 4. Characterization of sediments in two Mauritian freshwater reservoirs

    Magister-uppsats, Limnologi; Institutionen för biologisk grundutbildning

    Författare :Joel Segersten; [2010]
    Nyckelord :Mauritius; sediment; tropical; freshwater reservoir; internal loading; nutrient loading;

  7. 5. The debate on greenhouse gas emissions from freshwater reservoirs: Policy implications and opportunities for action

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Kirsi Mäkinen; [2009]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : This paper explores freshwater reservoir greenhouse gas emissions from a policy perspective. Existing science on reservoir emissions indicates that reservoirs can emit significant amounts of greenhouse gases and this is of particular concern for tropical reservoirs. LÄS MER
