  1. 1. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Alexander Lindblad; [2022]
    Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

  3. 2. Den flytande ön : gestaltningsförslag för en flytande modul med ekologiska förstärkningsåtgärder vid Norr Mälarstrand i Stockholm

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Anna Joos; [2022]
    Keywords : biodiversitet; ekologiska förstärkningsåtgärder; exploatering; förhöjda havsnivåer; förtätning; förlorade landytor; hållbara städer; klimatförändringar; urbanekologi; vattenkvalitet;

    Abstract : Runt om i världen sker idag stora landförluster till följd av förtätning av städer, exploatering av natur och land, förhöjda havsnivåer och kusterosion. Det resulterar i större konkurrens om de resterande landytorna; där de gröna ytorna ofta prioriteras lågt. Minskade naturarealer leder till försvagade habitat och ekosystem. READ MORE

  4. 3. Hydraulic Erosion Simulation on the GPU for 3D terrains

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sebastian Isheden; [2022]
    Keywords : Hydraulic Erosion; 3D erosion; CUDA; erosion; simulation; Vatten Erosion; 3D erosion; CUDA; erosion; simulering;

    Abstract : Erosion is the action of various natural processes, such as water flow, wind and gravity, that displaces material from one area to another. Creating physically-based models of these complex phenomena has been a major challenge in creating realistic terrain in video games in a fast way, without having a 3D artist model the terrain by hand.

  5. 4. An investigation of detecting potholes with UAV LiDAR and UAV Photogrammetry

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Linus Hedenström; Sebastian Eriksson; [2021]
    Keywords : UAV; LiDAR; photogrammetry; potholes; point clouds; SfM; paved; pavement; road; drone; UAV; LiDAR; fotogrammetri; potthål; drönare; asfalt; väg; punktmoln; SfM;

    Abstract : Potholes are caused by erosion and as such always emerging on our roadnetwork. Potholes may not only cause great damages to vehicles, but can alsocause road accidents, which in the worst case are fatal. READ MORE

  6. 5. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Daiki Makii; [2020]
    Keywords : Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

    Abstract : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.
