1. 1. Impact of Extreme River Flows on Bridges An Application to River Lagan in Ljungby Municipality, Sweden Using HEC RAS

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Assad Mohammad Tahir; [2022]
   Nyckelord :HEC RAS; Extreme River Flow; River Bridges; Ljungby; Lagan; Climate Change.; Technology and Engineering;

   Sammanfattning : The role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour.

3. 2. Critical perspectives: North Sea offshore wind farms. : Oral histories, aesthetics and selected legal frameworks relating to the North Sea.

   Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

   Författare :Joanne Moss; [2021]
   Nyckelord :Aesthetics; Coastal; Decay; Decommission; Development permission; European Landscape Convention; Fluid dynamics; Horizon; Industrial; Judicial review; Marine management; Maunsell; Monopile; NASA; North Sea; Offshore; Oral history; OSPAR; Scotland; Scour; Sealand; Sea plumes; Seascape; Sediment; SPM; Suspended particulate matter; Transience; Trawler; Turbine; United Kingdom; Wind farm.;

   Sammanfattning : The study is developed from five in-depth interviews with individuals from different walks of life who have interacted significantly with the North Sea. The study discusses change in the North Sea specifically in the development of fixed turbine wind farms and their physical and aesthetic effects. LÄS MER

4. 3. Evaluation of Local Scour along Rönne Å at Ängelholm

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Mohamed Fainaz Mohamed Inamdeen; [2020]
   Nyckelord :HEC RAS; Rönne å; Bend scour; Contraction scour; Abutment scour; River flow; HEC 18; Technology and Engineering;

   Sammanfattning : Riverbed scouring is an emerging problem aligned with higher frequent river discharges, experiences in a short period of time with shifting climate conditions. This problem brings a huge challenge to relevant authorities to safeguard river stability and hydraulic structures. LÄS MER

5. 4. Jet Stream Velocity fromAzipod on Stadsgården : A Litterature Study of PIANC W.G. 180Application for Stadsgården

   Master-uppsats, KTH/Marina system

   Författare :Viking Alex Schumacher; [2018]
   Nyckelord :;

   Sammanfattning : The ferry line company VIKING LINE has put in an order for a new vessel with a planned delivery for the year 2020. The vessel will berth and depart daily from the Stockholm port, Stadsgården. The vessel is equipped with two 10 MW Azipod propeller systems. LÄS MER

7. 5. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Tetsuro Goda; [2017]
   Nyckelord :Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

   Sammanfattning : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. LÄS MER
