WAVE FORCE AND NECESSARY HEIGHT OF WAVE SPLASH BARRIER ON BLOCK MOUND SEAWALL FOR A COASTAL ROAD

Abstract

  Two-dimensional hydraulic model tests were conducted to reveal the characteristics of the wave overtopping and the wave force on a wave splash barrier on a block mound seawall constructed for a coastal road. Numerical analysis by MPS methods were also carried out to estimate the hydrodynamic force on a running vehicle by wave action. Based on the test results, the necessary height of a wave splash barrier was shown as a function of the incident wave height. Wave pressure on a wave splash barrier can be calculated by Goda's formula with the modification factors.
