  1. 1. Pluvial urban flooding in a densified Sweden : do sustainable flood management and densification fit together?

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Helena Arro; [2023]
    Nyckelord :urban flooding; pluvial urban flooding; sustainable urban flood management; technological fix; densification;

    Sammanfattning : Pluvial urban flooding occurs in many parts of the world, including Sweden, often with severe consequences. Climate change and increased urbanization exacerbate the risk of urban flooding, and traditional urban drainage systems are unable to keep up. LÄS MER

  3. 2. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

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

    Författare :Oskar Ahlstedt; [2022]
    Nyckelord :Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Sammanfattning : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. LÄS MER

  4. 3. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

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

    Författare :Fanny Jeppsson Stahl; [2022]
    Nyckelord :Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

    Sammanfattning : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.

  5. 4. Intensiv nederbörd och pluviala översvämningar i Umeå

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elsa Lindgren; [2022]
    Nyckelord :Extreme precipitation; pluvial floods; climate change; solid surfaces; Umeå; extrem nederbörd; pluviala översvämningar; klimatförändringar; hårdgjorda ytor; Umeå;

    Sammanfattning : During intensive rainfall, the ground is at risk of flooding if the water has no opportunity to infiltrate into the ground or drain. Cities are most heavily affected by such pluvial floods due to their predominantly solid surfaces. LÄS MER

  7. 5. Dagvattenhantering vid flaskhalsområden : Klimatförändringar och vägen mot hållbar dagvattenhantering i Bollnäs

    M1-uppsats, Högskolan i Gävle/Miljövetenskap

    Författare :Linnéa Jonsson; Amanda Leima; [2020]
    Nyckelord :stormwater; climate change; bottlenecks; stormwater management; dagvatten; klimatförändring; dagvattensystem; flaskhalsar;

    Sammanfattning : Flooding from extreme rainfall is already taking place today in Sweden's urban areas. In order tocreate sustainable stormwater management that reduces the risk of flooding, various factorsshould be taken into account such as the choice of method for management. Bottlenecks in thestormwater system mean wells with undersized outlet pipes. LÄS MER
