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

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Abstract : 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.

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

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Abstract : 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. READ MORE
