Dear Authors,
Although your manuscript received relatively good comments, your responses arrived close to the deadline and possible reactions from the referees and discussants were not allowed any longer (I solicited your preliminry responses on March 15th). Moreover, depending on your revised manuscript, a possible second round of reviews may be advised.

Dear Authors,
Please note that referees have still made some comments on your revised version and also raised some key points that require attention for final decision on acceptance of the paper. Moreover, and also very important, both referees stressed that fact that the usage of English language is rather poor and also some part require to be presented in a clearer way to the reader. Please, ask help from a native English speaker.

Dear Authors,
Your additional revisions have made the manuscript now acceptable for final publication in HESS. Congratulations!
