  1. 1. Estimation of flood risk and cost-effective mitigations : A case study in Tierp

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Anton Blomqvist; Stephanie The; [2023]
    Keywords : Flood risk assessment; EAD; CADSS; MIKE21;

    Abstract : Climate change is predicted to alter the rainfall patterns in the future, and extreme rain events with large rainfall volumes will become more frequent and intense which increases the flood risk. A clear trend can be seen, where more and more people decide to relocate from rural to urban areas. READ MORE

  3. 2. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln

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

    Author : Prajwol Prajapati; [2022]
    Keywords : Hydrodynamic modelling; water quality; PFAS; PFOS; PFHxS; MIKE 3 FM; Ekoln; Fyrisån;

    Abstract : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. READ MORE

  4. 3. Sensitivity analysis of a generic urban flow model : 2D modelling with empirical hyetographs and CDS rain

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Granlund; [2022]
    Keywords : Input parameters; initial water content; antecedent moisture content; impervious surfaces; topography; empirical hyetographs; design storms;

    Abstract : Severe flooding events in recent years have underlined the importance of accurate hydrological modelling in urban areas. There are many important parameters relating to both the rainfall distribution and properties of the land on which the rain falls that controls the impacts of the rain event. READ MORE

  5. 4. How design storms with normally distributed intensities customized from precipitation radar data in Sweden affect the modeled hydraulic response to extreme rainfalls

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

    Author : Daniel Elfström; Max Stefansson; [2021]
    Keywords : cloudbursts; cloudburst mapping; spatial rain variation; pluvial flooding; hydraulic response; Swedish precipitation radar data; idealized urban catchment; hydrodynamic modeling; skyfall; skyfallskartering; gaussisk regnfördelning; spatial regnvariation; pluvial översvämning; hydraulisk respons; svensk nederbördsradardata; idealiserat urbant avrinningsområde; hydrodynamisk modellering;

    Abstract : Intense but short-term cloudbursts may cause severe flooding in urban areas. Such short-term cloudbursts mostly are of convective character, where the rain intensity may vary considerably within relatively small areas. Using uniform design rains where maximum intensity is assumed over the whole catchment is common practice in Sweden, though. READ MORE

  6. 5. Calibration of a 2D hydrodynamic model for flood inundation extent using aerial photographs : A case study of the Hallsberg flood event in 5-9 September 2015

    University essay from KTH/Vattendragsteknik

    Author : Alexandros Chatzakis; [2017]
    Keywords : MIKE 21; flood modelling; calibration; infiltration module; inundation; aerial photographs; MIKE 21; översvämnings modellering; kalibrering; infiltration modul; flygbilder;

    Abstract : Alteration of rainfall patterns is one major impact of climate change. Rainfall events with big precipitation volumes under short periods of time are predicted to become even more frequent in higher latitude regions, including Sweden. READ MORE
