Dear Authors,

The referees have raised several issues about your manuscript, which you have generally addressed in your replies in a satisfactory manner. Please change your manuscript accordingly before resubmission.
Some additional comments from my side:
• Referee #2 raised the issue of your conference paper 'How to Use COMSOL Multiphysics for coupled dual-permeability hydrological and slope stability modeling' from the 3d Italian workshop on landslides. Having looked at this publication, I agree with the referee that this publication should be mentioned in your manuscript, but does not preclude your publication in HESS.
• Both referees stated that a sensitivity study on your chosen forcing and model parameters would strengthen the manuscript (see your answer 9 to referee #1, and your answer 3 to referee #2). While I agree with the authors that detailed sensitivity studies are beyond the scope of your manuscript, I suggest adding to the conclusions a section which reflects more in depth on the choice of your most important (fixed) parameters and forcing and their potential influence on the results if varied.
• Please also include your answers 8 and 30 to referee #2 in your revised manuscript at the appropriate places.

Yours sincerely,

Uwe Ehret

Dear Authors,

Both reviewers acknowldege the improvements in the revised version of the manuscript. I agree with reviewer #2 that you stay below the potential of your study by not including a detailed sensitivity study on the forcing and model parameters on your result. However, the study is nevertheless worth being published after minor revisions.
Please include the comments of reviewer #2 in a revised version of your manuscript, especially consider answers 8 and 30 (I mentioned that already in my last decision) and indicate the changes where made.

Yours sincerely,
Uwe Ehret
