To investigate mitigation strategies, we simulate waves and a flood-like situation from two-dimensional (2D) dam-break flow with a ramp section at the end of the channel using smoothed particle hydrodynamics (SPH). We analyse the effects of ramps with various topographies to reduce the pressure on structures exerted by the wave. Structures of ramp surfaces influence flow behaviour significantly, absorbing kinetic energy of the wave. Increasing the ramp angle reduces the impact on the structure.
