As it became clear from the comments of 2 reviewers, there several points where significant clarification is needed. You partly address these and the other points, which were raised by the reviewers, in your response. I am optimistic that a revision of this manuscript might become acceptable for HESS. A central issue for the revision is the clarifications which are needed to make it easier to understand exactly what you have done. Another issue is English word selection and expression which makes difficult to understand the presented findings and conclusions. Due to the revisions needed, the revised version will be send out for review again.

The manuscript can be accepted now.
