  1. 21. High resolution modelling and analysis of urban flooding

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Angelos Kosmas; [2019]
    Nyckelord :Tokyo Storm Runoff model; TSR; urban flooding; Augustenborg; stormwater management; pipe networks; Technology and Engineering;

    Sammanfattning : The predictions on climate change and precipitation patterns in the near future, as well as urbanization, lead to higher volumes of runoff, which in turn challenge the sustainability and functionality of urban drainage pipe networks. In order to understand how these changes will affect the existing infrastructure in urban areas, integrated urban water model software are needed to identify effective solutions to minimize urban flooding.

  3. 22. Runoff modelling and assessment of treatment wetland performance using a triangular form based multiple flow algorithm

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Clara Hübinger; [2019]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : Eutrophication is one of the biggest threats to aquatic ecosystems. As nutrient load increases in marine environments in the Öresund and Baltic Sea and dead zones grow, Swedish municipalities further their efforts in limiting the amount of nutrients delivered into those environments.

  4. 23. Impact of Extreme Rainfall Event over Swedish Urban Catchments : A study on catchment characterization in the context of Aerial Reduction Factor and storm movement

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

    Författare :Md Didarul Alam Tusher; [2019]
    Nyckelord :;

    Sammanfattning : The design practices of urban hydraulic structures are required to be based on enough safety measures in addition to cost efficiency for sustainable development. Overestimation of catchment runoff generated from a storm event can increase the project cost unnecessarily. LÄS MER

  5. 24. Flow simulation in MIKE URBAN based on high-resolution X-band radar data

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Sammanfattning : 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. LÄS MER

  7. 25. The influence of storm movement and temporal variability of rainfall on urban pluvial flooding : 1D-2D modelling with empirical hyetographs and CDS-rain

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jimmy Olsson; [2019]
    Nyckelord :pluvial flooding; flood modelling; 1D-2D modelling; MIKE FLOOD; MIKE 21; MIKE URBAN; storm movement; temporal variability; hyetograph; design storm; Chicago Design Storm; CDS-rain; pluviala översvämningar; översvämningsmodellering; 1D-2D modellering; MIKE FLOOD; MIKE 21; MIKE URBAN; molnrörelse; hyetograf; typregn; Chicago Design Storm; CDS-regn;

    Sammanfattning : Pluvial floods are formed directly from surface runoff after extreme rain events. Urban areas are prone to suffer from these floods due to large portions of hardened surfaces and limited capacity in the stormwater infrastructure. Previous research has shown that catchment response is influenced by the spatio-temporal behaviour of the rainstorm. LÄS MER
