Abstract/Summary Tsunamis often devastate the coastal infrastructure and also result in large transport of sediments in the coastal regions. Qualification of sediment transport across and nearshore is attempted from the available sediment transport formulae that use free stream velocities as input. DHI-MIKE numerical model is used to obtain velocities due to tsunami event of December 2004, on the southeast coast of India. Sediment transport using estimated velocity is calculated in the study region. Due to the large water depths and small tsunami wave heights in the offshore, the sediment transport is assumed to be predominantly a bed load transport outside surfzone. Bed load sediment transport equations outside the surfzone are used in this study. This paper attempts to estimate the sediment transport due tsunami induce velocities in the near shore region in the vicinity of a submarine canyon.
