  1. 16. Efficiency of sustainable urban drainage systems during flash floods

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Snærós Axelsdóttir; [2022]
    Keywords : Bioretention Cell; Rain Garden; Infiltration Trench; Green Roof; Permeable Pavement; Stormwater runoff; Storm Water Management Model;

    Abstract : As the world’s population is migrating more into urban areas, landcover changes follow. Natural pervious areas are being converted to impervious areas, which when subjected to rain generates more stormwater runoff. READ MORE

  3. 17. Hållbar dagvattenhantering i mittrefug : en studie av Västra Ringvägen i Västerås

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Ida Elgelind; Sandra Villner; [2022]
    Keywords : hållbar dagvattenhantering; mittrefug; gata; infiltrationsanläggning; gräsbeklätt dike; makadamdike;

    Abstract : Dagvattenhanteringen får allt större fokus i stadsplaneringen till följd av klimatförändringar och urbanisering. Städers kraftiga expansion med fler hårdgjorda ytor medför att den naturliga vattencykeln påverkas och större dagvattenmängder rinner av på ytan istället för att infiltrera. READ MORE

  4. 18. An analysis of the understanding of maintenance of nature-based solutions for urban stormwater management

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emma Knapik; [2022]
    Keywords : Flood adaptation; resilience; sustainability; green infrastructure; uncertainty; Översvämnings anpassning; spänstighet; hållbarhet; osäkerhet;

    Abstract : Urban stormwater management is necessary to protect human life and society from the dangers and damages associated with flooding from extreme weather events. Conventional measures of stormwater management utilise grey infrastructure to convey runoff away from urban areas, but due to increasing urbanization, aging of urban infrastructure, climatic variability, and flooding due to extreme weather events, these measures are often no longer sufficient.

  5. 19. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anna Träff; [2022]
    Keywords : Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

    Abstract : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE
