  1. 1. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yanhe Zhou; [2023]
    Nyckelord :Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

    Sammanfattning : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. LÄS MER

  3. 2. Changes in Gishwati-Mukura Forest and effects on biodiversity, floods, and landslides - recommendations for sustainable forest management

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Elisabeth Claesson; [2023]
    Nyckelord :Rwanda; Gishwati-Mukura; Rainforest; Natural forest cover; Deforestation; Biodiversity; Flood; Landslide; Biology and Life Sciences;

    Sammanfattning : Rainforests are of great importance for biodiversity and several ecosystem services. In Rwanda, a considerable decline in rainforest covers have been observed during the last decades. The Gishwati-Mukura Forest is one of the rainforests in Rwanda that has experienced a substantial reduction in forest cover, 99.4 %. LÄS MER

  4. 3. Floods and landslides in the Bakokwe catchment, Rwanda: Causes, consequences, and future challenges

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Saga Kallner; Martine Ulvtorp; [2022]
    Nyckelord :Flooding; Rainfall; Landslide; Rwanda; Bakokwe; Causes; Consequences; Future challenges; Technology and Engineering;

    Sammanfattning : Rwanda is highly exposed to floods and landslides due to intense precipitation, rapid population growth, varied topography and agricultural growth. One of the most vulnerable areas is the Nyabarongo catchment. A subcatchment of the Nyabarongo catchment, Bakokwe, was chosen as a case study for this thesis. LÄS MER

  5. 4. Surface crevasses on Svalbard: Spatial Distribution Analysis with Focus on the Lomonosovfonna Ice Cap

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Monika Hawrylak; [2021]
    Nyckelord :crevasses; spatial distribution; model; glacier velocity; Lomonosovfonna; Svalbard;

    Sammanfattning : Understanding the formation mechanics of glacial crevasses is crucial in a variety of glacial applications. Besides being a serious safety hazard during field campaigns, crevasses influence calving rates, mass balance, and the hydrological network of glaciers. LÄS MER

  7. 5. Prediktering av grundvattennivå i område utan grundvattenrör : Modellering i ArcGIS Pro och undersökning av olika miljövariablers betydelse

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Olof Lood; [2021]
    Nyckelord :groundwater; groundwater level; modeling; ArcGIS; machine learning; Random Forest; Forest-based Classification and Regression; Model Builder; grundvatten; grundvattennivå; modellering; ArcGIS; maskininlärning; Random Forest; Forest-based Classification and Regression; Model Builder;

    Sammanfattning : Myndigheten Sveriges Geologiska Undersökning (SGU) har ett nationellt ansvar för att övervaka Sveriges grundvattennivåer. Eftersom det inte är möjligt att få ett heltäckande mätstationssystem måste grundvattennivån beräknas på vissa platser. LÄS MER
