  1. 1. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Francesca Polato; [2021]
    Keywords : hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Abstract : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

  3. 2. 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

  4. 3. Sensitivity analysis of grate inlet representation and a comparison of two coupled hydraulic models for urban flood simulation

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Daniel Lundqvist; [2020]
    Keywords : Urban flood models; 1D-2D coupled models; MIKE FLOOD; FLO-2D; inlet grates; manholes;

    Abstract : Urban flood models are an important tool in designing and analyzing municipalities sewer drainage systems and predicting the effect of potential extent and depth of future floods. In urban areas, coupled 1D-2D flood models are particularly useful as they can represent the surface- and sewer system and their interactions. 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
