Investigation of Shock Wave Pressure Transmission Patterns and Influencing Factors Caused by Underwater Drilling Blasting

Round 1

Reviewer 1 Report

1. Qualities of figures are very bad. All are faded with values not clear. Please replace all the figures with clear and high-quality figures.

2. How could dynamic viscosity values for air and water be the same as 8.9? Please support it with some relevant background.

3. It was said that shock wave travels faster in water because of the density of water but in numerical modeling for water-air interface reflecting boundary condition is chosen, how this change inthe shock wave velocity is addressed?

4. What is the effect of horizontal stresses acting over the rockmass?

5. Is numerical model is a scaled model? If yes, what is the scaling factor used? and if not why the validation of field data and numerical analysis is shown in different scales in figure 7?

Reviewer 2 Report

This manuscript investigates the transmission patterns and influencing factors of underwater drilling blast shock wave pressure. Both field monitoring data and numerical simulation results are presented. In general, this manuscript is well written and organized. It can be considered for possible publication in Water after a minor revision. The revision should take account of the specific comments listed below.

(1)  The title of this manuscript can be more concise.

(2)  In the Introduction, the authors simply state that the current theoretical studies on shock waves of underwater drilling blasting still have room for improvement, but did not describe or review the state of the art of the current theoretical studies on this topic.

(3)  Please present a literature review on the transmission patterns of drilling blast shock waves in water and their influencing factors. Therefore.

(4)  A discussion on how the research findings can provide guidance for the safe control of underwater drilling blasting projects in inland waterways should be added.

(5)  The figure resolution needs to be improved.

(6)  The empirical equation for the peak pressure of the underwater drilling blasting shock wave is established based on the project in Guoyuan Port, is this equation applicable for other projects at different sites?

(7)  The first conclusion needs to be described carefully, as there should be a restrictive condition for the accuracy or applicability of the equation established.

Reviewer 3 Report

The manuscript titled "Investigation of the pressure transmission patterns and influencing factors of shock waves caused by underwater drilling blasting" is ready for publication after the following minor change:

1. Fig 7 doesn't clearly show the peak pressure for the subplots. I suggest the authors to add color to the subplots and add text with the max. pressure inside the figure.

Answer: Thank you for your valuable advice. The small figure and the large figure in Figure 7 showed the same simulation result, the different ordinates were used to in the two figures in order to facilitate data observation. If the curve color was changed in the small figure, two pressure curves with different colors will appear in the legend, which will cause misunderstanding to readers.
