  1. 21. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Annejet Tuinstra; [2021]
    Nyckelord :wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Sammanfattning : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. LÄS MER

  3. 22. Effects on traffic work during demand-based collection of waste compared with collection at fixed intervals

    Kandidat-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Rebecca Gustafsson Linder; Paulina Lindqvist; [2021]
    Nyckelord :logistik; returlogistik; avfallshanteringslogistik; avfallshämtning; trafikarbete; transportplanering; ruttplanering; GIS; geografiska informationssystem; hållbarhet;

    Sammanfattning : Avfallshämtningen är ett komplext problem som ställer mängder av logistiska krav och bör tillgodose kundens behov om att få sina sopor upphämtade och tömda i rätt tid. Samtidigt bör onödigt trafikarbete minskas för att uppnå en mer hållbar avfallshämtning. LÄS MER

  4. 23. Centre-peripheral regional development and human capital distribution: peripheral experience within functional region of Stockholm

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Författare :Johan Ovsiannikov; [2021]
    Nyckelord :centre-periphery; regional development; knowledge economy; spatial sorting human capital; Social Sciences;

    Sammanfattning : Studying knowledge-intense regional development from the perspective of classified periphery fills an identified gap in analysis and practice. It illustrates challenges, possibilities, and nuances current trajectory of centre-peripheral development. LÄS MER

  5. 24. Spatiotemporal change of stream and wetland features over 140 years in an agricultural catchment in southern Sweden : an assessment of historical maps in GIS

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Linnea Lindelöf; [2021]
    Nyckelord :historical map; wetland; stream; GIS; sinuosity index; land cover change; georeferencing; vectorizing;

    Sammanfattning : The Swedish agricultural landscape has historically changed by draining wetlands and hydromorphological impacts by straightening and redirect watercourses. Drainage has been a part of Sweden’s agricultural history, dating back to the 13th century with its peak in the 19th and 20th centuries. LÄS MER

  7. 25. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Gabriella Corbee; [2021]
    Nyckelord :Phosphorus retention; sedimentation; hydraulic load; Fosforavskiljning; sedimentation; hydraulisk belastning;

    Sammanfattning : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. LÄS MER
