Haslett, S.K and Wong, B.R (2021) A Froude number approach to the possible causes of incipient boulder displacement due to wave impact. In: Persidangan Fizik Kebangsaan (PERFIK) / Malaysian National Physics Conference, 29 - 30 June 2021, online.
Abstract
Storm waves and tsunamis have been responsible for the movement and deposition of boulders located near or at a shore. Nott proposed a set of formulas to calculate the minimum incident wave velocities required to dislodge cuboid-shaped boulders. These formulas depend on boulder properties, local terrain, water wave parameters and mechanism of dislodgement. Further, Nott proposed a formula to compute the wave height corresponding to the wave velocity, and including a parameter depending on whether the wave arose from a storm or a tsunami. The dislodgement formulas have been improved and extended (cf. Haslett and Wong, Nandasena) and references therein) to include additional boulder configurations. Recently, Nott’s approach to inferring wave height and wave type has been criticised. This work is a preliminary study to link boulder- and wave-parameters to a Froude number which might be useful as an alternative approach to deciding between storm waves and tsunami waves as a cause of boulder displacement.
