  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. 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

  6. 5. 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
