  1. 1. Controls over stream temperature in a northern boreal landscape

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Oskar Damström; [2023]
    Nyckelord :Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Sammanfattning : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. LÄS MER

  3. 2. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation

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

    Författare :Martin Dahlin; [2022]
    Nyckelord :Streamflow information; Manning s estimation; rating curve; hydrographs; Vattenföring; avbördningskurva; hydrograf; Mannings ekvation;

    Sammanfattning : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. LÄS MER

  4. 3. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Lara Sánchez Calderón; [2022]
    Nyckelord :aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Sammanfattning : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. LÄS MER

  5. 4. Dynamic streams in a pre-alpine catchment

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Andreas Sølberg; [2021-07-12]
    Nyckelord :Temporary streams; Streamflow; Stream mapping; Pre-Alpine catchment; Stream dynamics; Topographic wetness index; Upslope accumulated area;

    Sammanfattning : This thesis aims to investigate the factors controlling the dynamics of temporary streams, i.e., streams that do not flow throughout the year. Temporary stream hydrology is a relative unexplored scientific field. LÄS MER

  7. 5. Temporal Trends in Dissolved Inorganic Carbon in a Swedish Boreal Catchment

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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.
