11. Rheology of dense particle suspensions in linear over-damped flow
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

12. Surf Simulation with the Shallow Water Equations : Coupling of a surfer model to a shallow water wave
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)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.

13. 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 landskapsläraSammanfattning : 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
14. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : 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.

15. Wave Damping by Vegetation at Bunkeflo Salt Meadows - Applying an empirical model based on plant biomass
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : 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
