I received comments from three reviewers, reviewers 1 and 3 suggested "minor revisions", and reviewer 2 suggested "major revisons". Even though the reviewer 1 suggested minor revisions, he/she asked many questions and made a lot of comments. It is not a minor task to answer the questions and the comments, also it is not "minor revisions" to revise the manuscript accordingly. Therefore, I suggest "major revisions" to the manuscript, and will be further reviewed by the reviewers and myself.

All the reviewers pointed out the manuscript's language issue, and the significance or/and novelty is not well presented, which is a key to be accepted by HESS. The reviewers also provided detailed comments and suggestions to revise the manuscript. After receiving the comments, I carefully read the manuscript again, and concur with the comments. Therefore, I suggest to answer the questions and comments in detail and revise the manuscript accordingly.

I received review comments from two reviewers, both suggested "publish subject to technical corrections" and they thought the authors had well answered their comments/questions and revised the manuscript accordingly. They thought the manuscript was ready to be published subject to some technical revisions. After receiving the comments, and I carefully read the manuscript again and concur with the reviewers. Please answer the comments and questions made by the two reviewers in detail and revise your manuscript accordingly.
