  1. 1. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Vindenergi

    Författare :Tula Strotz; [2023]
    Nyckelord :Agroforestry; contouring grass rows; Guinea grass; nutrient losses; Vietnam; Gräsbarriärer; Höglandsodling; näringsförlust; Träjordbruk; Vietnam;

    Sammanfattning : The population in the high mountains of the northwest provinces of Vietnam belongs to the poorest population in the country. Among the reasons behind this are the high frequency of minority groups in the region and the infertile soils of the steep slopes. LÄS MER

  3. 2. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :June Johansson; [2023]
    Nyckelord :Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Sammanfattning : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. LÄS MER

  4. 3. Flood mitigation at catchment scale: assessing the effectiveness of constructed wetlands

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

    Författare :Elin Ekström; [2023]
    Nyckelord :Nature-based solutions; wetlands; catchment; performance indicators; flood management; hydrological modeling; SWAT; Naturbaserade lösningar; våtmarker; avrinningsområde; nyckelindikatorer; översvämningshantering; hydrologisk modellering; SWAT;

    Sammanfattning : Considering the potential for natural wetlands to store and retain water in the landscape,restored and constructed wetlands are increasingly implemented as Nature‐BasedSolutions (NBS) to mitigate downstream flooding. However, there is a frequent lack ofknowledge of the performance of NBS, and particularly wetlands, and how to best selectperformance indicators to measure their effectiveness. LÄS MER

  5. 4. Developing a Rainfall-Runoff Routing Model using  Spatially Distributed Travel Times : Modelling a Cloudburst Event in an Urban Catchment

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

    Författare :Sara Ekeroth; [2022]
    Nyckelord :Excess rainfall; Runoff routing; Cloud burst; Pluvials; GIS; ArcPy; Effektiv nederbörd; Avrinningsmodell; Skyfall; Pluviala översvämningar; Geodata; ArcPy;

    Sammanfattning : The future holds challenges for urban areas when it comes to handling pluvial floodings, occurring when the rainfall intensity exceeds both the man-made and natural infiltration and drainage capacity. To gain understanding of the effects and needed measures, tools for modelling the urban response to events such as cloudbursts are needed. LÄS MER

  7. 5. Considering future precipitation in delineation locations for water storage systems - Case study Sri Lanka

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

    Författare :Kanchana Bandaranayake; [2021]
    Nyckelord :Geography; Geographical Information Systems; Physical Geography; Locating new water resources; Water scarcity; Consideration of climatic changes; Future precipitation; Pairwise comparison; Sri Lanka; Earth and Environmental Sciences;

    Sammanfattning : Demand for the usable water is accumulating globally in parallel with the population growth and the industrial revolution. Nevertheless, availability and accessibility of the usable water is progressively subsiding due to many environmental and socio-economic reasons. LÄS MER
