  1. 26. Characterization and modeling of hydrology and climatology in paramo ecosystems in Colombia : A study of the paramos and climate change impact on these ecosystems as a water resource

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Lovisa Nilsson; Julia Tholander; [2022]
    Nyckelord :paramo; hydrology; climate change; precipitation; discharge; modeling; characterization; HBV; ENSO; paramo; hydrologi; klimatförändringar; nederbörd; avrinning; modellering; karaktärisering; HBV; ENSO;

    Sammanfattning : Paramos are unique ecosystems situated in the tropical Andes at an elevation of 2800-4800 meters above sea level. They are home to a variety of endemic species and have a great water regulating capacity and supply around 80 % of the population in Colombia with freshwater. LÄS MER

  3. 27. Hur hänger det ihop? : En hydrologisk detaljstudie av ytvattenkonnektivitet mellan sjöar och vattendrag i Västerbottens län

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

    Författare :Gustav Högberg; [2022]
    Nyckelord :Earth science; Hydrology; connectivity; surface water; highest coast line; GIS-analysis; rivers; river networks; lakes; geovetenskap; hydrologi; konnektivitet; ytvatten; högsta kustlinjen; GIS-analys; vattendrag; vattendragsnätverk; sjöar;

    Sammanfattning : Surface water hydrology is a deeply studied subject, yet there are barely any studies concerning surface water connectivity, neither micro- nor macro scale. With the explosive development of GIS over the past decade, tools for measuring and analysing rivers and lakes are inumerable. LÄS MER

  4. 28. 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

  5. 29. Riparian buffer zones in agricultural landscapes : Their status today and their future as an ecological tool in Sweden

    Master-uppsats, Karlstads universitet

    Författare :Mikaela Ignatiou Hadjicharalambous; [2021]
    Nyckelord :Riparian buffer zones; agriculture lanscapes; ecological tool; streams; kantzoner; lantbrukslandskap; ekologisk vertyg; vattendrag;

    Sammanfattning : The application of intensive farming and cultivation practices, resulting in large-scale modification of the hydrology of streams and rivers and of the natural vegetation, has increased the need to find ways to mitigate the negative impact of this habitat degradation. Suitable design and creation of riparian buffer zones in agriculture areas, is by many considered the best remedial measure. LÄS MER

  7. 30. Monitoring wetland cover changes during the past two decades within the protected areas of the Sudd wetland in South Sudan using MODIS data

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

    Författare :Charlotta Ruuskanen; [2021]
    Nyckelord :Physical Geography and Ecosystem analysis; MODIS; NDVI; Sudd Wetlands; Wetland Cover Classification; White Nile Hydrology; Armed Herder-Pastoralist Conflict analysis; Earth and Environmental Sciences;

    Sammanfattning : The Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. LÄS MER
