  1. 1. 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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE

  3. 2. 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

  4. 3. Flow simulation in MIKE URBAN based on high-resolution X-band radar data

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Lisa Olsson; [2019]
    Keywords : X-band radar; MIKE URBAN; modelling; rainfall-runoff; online control; Technology and Engineering;

    Abstract : Radar har använts sedan 1940-talet för att mäta och övervaka nederbörd. Under de senaste åren har X-bandradarn visat sig vara ett verktyg som kan förbättra indata till avrinningsmodellering inom urbana avrinningsområden. Detta tack vare sin höga upplösning i tid och rum jämfört med andra radarer som används vid nederbördsmätning. READ MORE

  5. 4. Watershed delineation for runoff estimations to culverts in the Swedish road network : a comparison between two GIS based hydrological modelling methods and a manually delineated watershed

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Iris Behrens; [2017]
    Keywords : GIS; hydrological modelling; watershed: single flow direction algorithm; multiple flow direction algorithm; climate change adaption; Earth and Environmental Sciences;

    Abstract : The anticipated climate changes are predicted to alter the precipitation patterns in Sweden. Increased episodes of intense short-duration rainfall and higher intensities of day long-duration rainfall are expected. Road sections are often a target of flooding, causing impassable roads, due to the lack of capacity of drainage systems. READ MORE

  6. 5. Planning support for reducing risks related to flooding : A case study of flood response in Kista residential area and Igelbäcken stream, Sweden

    University essay from KTH/Mark- och vattenteknik

    Author : Kajsa Lundgren; [2017]
    Keywords : Planning support; blue green solutions; hydrodynamic modelling; MIKE FLOOD; climate change adaption; land use change; Planeringsstöd; blå-gröna lösningar; hydrodynamiskmodellering; MIKE FLOOD; klimatanpassning; markanvändning;

    Abstract : Flooding has been identified as the most widespread and most frequently occurring natural disaster by the United Nation. Sweden is no exception when it comes to being affected by flooding, and several major flood events have been seen in recent years. READ MORE
