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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emmanuel Ekwu; [2021]
    Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER

  4. 3. 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

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Glacial lake flood hazard assessment and modelling : a GIS perspective

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

    Författare :Maimoona Zehra Jawaid; [2017]
    Nyckelord :moraine dammed lake; Himalayas; Bhutan; GIS; hazard assessment; dynamic flood model; glacial lake; Physical Geography; ecosystem analysis; digital elevation model; GEM; Earth and Environmental Sciences;

    Sammanfattning : High mountain regions have experienced decreased glacier stability due to varying climate conditions. As glaciers melt, they are being replaced by glacial lakes of different sizes, some of which are prone to outburst flooding, and have caused catastrophic damage to downstream settlements and infrastructure.

  7. 5. A dynamic and spatially distributed rainfall runoff model - Developing a model for overland flow in GIS, based on a multiple flow direction algorithm

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Hampus Nilsson; [2017]
    Nyckelord :flood modelling; GIS; TFM; surface runoff; multiple flow; flow routing; Technology and Engineering;

    Sammanfattning : Climate change is expected to cause 20-25% heavier rainfall in Sweden which, in combination with the ongoing urbanization, increases the probability of flooding in urban areas. These floods may cause large infrastructural damage and economical costs. LÄS MER
