  1. 1. Sensitivity analysis of pluvial flood modelling tools for dense urban areas : A case study in Lundby-Lindholmen, Gothenburg

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

    Author : Johanna Eriksson; [2020]
    Keywords : Flood Modelling; MIKE FLOOD; Sensitivity Analysis;

    Abstract : As a result of the global climate change, extreme precipitation is occurring more frequently which increases the risk of flooding, especially in urban areas. Urbanisation is widely discussed regarding urban flooding where an increase of impervious surfaces limits the infiltration and increases the surface runoff. READ MORE

  3. 2. Hydraulic modelling of the vulnerability for compounding high sea levels and high river discharge on the Swedish coastline

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Hannah Berk; [2020]
    Keywords : Coastal floods; combined compound flood events; fluvial floods; LISFLOOD-FP; hydraulic modelling; Earth and Environmental Sciences;

    Abstract : Coastal floodplains are at risk for combined high discharge and sea level events. Consequences when they occur can be several magnitudes greater than the impact from any isolated event. READ MORE

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

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

    Author : Jimmy Olsson; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 4. Integrated hydrodynamic and socio-economic damage modelling for assessment of flood risk in large-scale basin : The case study of Lower Chao Phraya River Basin in Thailand

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Phat Pumchawsaun; [2018]
    Keywords : Chao Phraya River Basin; flood risk assessment; 2D hydrodynamic model; fully 2D and coupled 1D 2D numerical methods; KULTURisk methodology; depth-damage functions;

    Abstract : Thailand has been often affected by severe flood events over the past century. The 2011’s Thailand Flood Catastrophe was the costliest in country’s history, and it was ranked to be the second most damaging natural hazard in the world in terms of economic losses. READ MORE

  6. 5. Potentials and limitations of 1D, 2D and coupled 1D-2D flood modelling in HEC-RAS

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Alexander Betsholtz; Beatrice Nordlöf; [2017]
    Keywords : Hydraulic modelling; HEC-RAS; 1D; 2D; 1D-2D; flooding; sub-grid; Technology and Engineering;

    Abstract : Hydraulic models can be used to predict the consequences of flooding events. In this project, three hydraulic models were constructed using the software HEC-RAS, and compared through a case study on Höje river catchment. READ MORE
