  1. 1. Surf Simulation with the Shallow Water Equations : Coupling of a surfer model to a shallow water wave

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anton Thorell; [2021]
    Nyckelord :;

    Sammanfattning : This thesis covers the subject of deriving and solving the system of partial differential equations known as the Shallow Water Equations (SWE), and coupling the solutions of this equation system to a simplified model of a surfer - or any floating object, with the right choice of parameters. The SWE are generally used to analyze fluid movement on shallow areas, such as ocean waves nearing the shore, and are derived from the Navier-Stokes equations and restricted to conservation of mass and momentum in a fluid.

  2. 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; 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

  3. 3. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
    Nyckelord :HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

    Sammanfattning : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

  4. 4. Wave Damping by Vegetation at Bunkeflo Salt Meadows - Applying an empirical model based on plant biomass

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Charlie van Houwelingen; Timothy Ley; [2021]
    Nyckelord :Coastal protection; nature-based solutions; salt marshes; salt meadows; sea level rise; wave damping; Technology and Engineering;

    Sammanfattning : Future sea level rise due to climate change increases the risk of coastal flooding and thus necessitates the building of dikes and other protective structures. Coastal vegetation can reduce the impact of waves on such structures by dissipating wave energy and hence reduce incoming wave heights. LÄS MER

  5. 5. 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.
