  1. 1. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Elias Johansson; [2024]
    Nyckelord :Tunnel water; tunnel construction; nitrogen; fertilizer; irrigation; Länshållningsvatten; Tunnelvatten; Tunneldrivning; Kvävegödsel; Bevattning;

    Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER

  5. 4. Uncertainties in characterising historical heatwaves in Europe

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Simon Abrahamsson; [2023-08-18]
    Nyckelord :;

    Sammanfattning : Heatwaves are periods of excessively hot weather which can pose a threat to both the people and the agriculture affected by them, for this reason it is important for us to understand and be able to predict heatwaves. This study will therefore investigate historical heatwaves in Europe and compare the quality of different 2m surface temperature datasets and examine the possibility of using 3D temperature data to identify heatwaves.

  7. 5. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Ivan Ruzic; [2023-06-21]
    Nyckelord :heat wave; urban trees; NDVI; remote sensing;

    Sammanfattning : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. LÄS MER
