  1. 1. Effects of Maintenance on the Efficiency of NBS for Urban Flood Management

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

    Författare :Julia Markström; [2023]
    Nyckelord :Stormwater management; Nature-Based Solutions NBS ; Maintenance; Efficiency; Runoff volume reduction; Dagvattenhantering; Natur-baserade lösningar; Underhåll; Effektivitet; Dagvattenreducering;

    Sammanfattning : As rain events are likely to intensify and the proportion of impervious areas in cities increases, greater demands are put on stormwater management. Nature-Based Solutions (NBS) have become more popular over the past decades to be integrated into the stormwater strategy in order to reduce the volume of runoff in cities. LÄS MER

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

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Daniel Elfström; Max Stefansson; [2021]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Prasanjaya Bandara Ekanayake; [2021]
    Nyckelord :Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

    Sammanfattning : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.

  5. 4. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Malin Strandberg; [2021]
    Nyckelord :Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

    Sammanfattning : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.

  7. 5. Nutrients spreading with cloudburst modeling

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

    Författare :Nikita Smiyanov; [2020]
    Nyckelord :MIKE21; 2D-modeling; nutrients; phosphorus; nitrogen; cloudburst; land-use; MIKE21; 2D-modellering; närsalter; fosfor; kväve; skyfall; markanvändning;

    Sammanfattning : Climate change and environmental disasters are strongly dependent. Humanity is facing considerable changes in environmental adaptions and remediation of contaminated sites. Water is a valuable resource that should be protected and prevented from hazardous influences. LÄS MER
