Round 1

Reviewer 1 Report

The authors have considered the anisotropy of the multilayered TIP seabed and investigated the dynamic response under wave-current loading. The reviewer would like to request the following clarifications to further improve the paper.

  • Section 4, Pg 12: The effect of current velocity U0 on the maximum pore pressure requires proper clarification. Further, please explain the rationale behind adopting a smaller averaged current velocity for the model input.
  • Please justify why the transient liquefaction can occur in fully saturated seabeds as opposed to the findings by Rahman [52] and Jeng [35].
  • The limitations of the present semi-analytical solution need to be highlighted. Perhaps, in a separate section?

Reviewer 2 Report

The paper discusses an interesting investigation of wave-current interaction on the dynamic response of the seafloor. The first chapters describe the theoretical backgroungd of the solution. Sequentially, the paper describes the detailed analytical solution of this specific dynamic problem in several variants. As a result, sensitivity plots are presented for changes in various parameters appearing in the solution. The conclusions evaluate the significant influences of each parameter. The only question I have about the whole paper is whether experimental verification is possible or, if measurements have been made in the past, how consistent they are with the solution presented by the authors. In general, I evaluate the paper as a result of good work and recommend it for publication.
