  1. 1. Hur avrinningskoefficienten varierar med återkomsttid - En jämförelse mellan fyra olika områden i Sverige

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Nina Enger; [2024]
    Nyckelord :Runoff coefficient; Return period; Modelling; MIKE ; Floodings; Technology and Engineering;

    Sammanfattning : As climate change progresses, heavy rainfall in Sweden is becoming more frequent and intense, coinciding with an increase in impermeable surfaces in urban areas. This raises the risk of flooding as drainage networks may exceed their capacity due to increased runoff. LÄS MER

  3. 2. Expectations and reality of sustainable stormwater management : A review of implementation of Nature-Based Solutions - A case study of Southern Stockholm

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

    Författare :Katarzyna Zofia Dziubanii; [2024]
    Nyckelord :Nature-based solutions; green infrastructure; ecosystem services; planning process; spatial planning; urban planning; stormwater management; sustainability; climate change mitigation; Naturbaserade lösningar; grön infrastruktur; ekosystemtjänster; planeringsprocess; fysisk planering; stadsplanering; dagvattenhantering; hållbarhet; klimatförändringar;

    Sammanfattning : The shrinking of permeable areas in favour of urban development is a phenomenon described in both scientific literature and policy documents. Changes in rainfall intensity and frequency following climate change are expected, but predicting the exact magnitude of these changes remains unclear. LÄS MER

  4. 3. Att förebygga översvämningar med hjälp av konceptet Sponge city : En fallstudie av Hemlingby i Gävle

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Johan Kjell; Filip Nilsen; [2023]
    Nyckelord :climate change; flooding; cloudburst; GIS; city planning; Sponge city; klimatförändring; översvämning; skyfall; GIS; stadsplanering; Sponge city;

    Sammanfattning : Climate change is predicted to cause an increase in cloudbursts and heavy precipitation, which makes urban flooding an issue that needs to be dealt with. The term Sponge city is a theory that intends to deal with urban flooding and worsening water quality in urban areas with absorption. LÄS MER

  5. 4. Surface Runoff on Green Urban Areas : A study on driving forces behind surface runoff generaiton

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

    Författare :Erik Nilsson; [2023]
    Nyckelord :Surface runoff; Hydrus; Urban green area; Soil Moisture;

    Sammanfattning : Recent flooding events, such as the one in Germany 2021 have caused irreversible damages to infrastructure and lives. The aftermath of events like these have underlined the importance of an accurate risk management by predicting them in urban areas. LÄS MER

  7. 5. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Anastasia Novikova; [2023]
    Nyckelord :HYDRUS; surface runoff; soil compaction; urban environments;

    Sammanfattning : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. LÄS MER
