Referees provided large number of comments, and recommendations for improvement. These are substantial and all of them have to be addressed adequately. Authors are invited not only to answer the referees, but also to show how they have accordingly revised the manuscript.
I wish the authors good luck.

One referee accepts the paser as is.
The second one writes:
"The authors have well modified the manuscript according to my comments. Thanks for the great efforts. Now this manuscript can be accepted for publication in HESS only after one minor revision.
Figure 1: please add longtidues and latitudes of the Wei River basin in this figure. Also, make clear what the colors are in the map. I think these are DEMs.
Best regards,"
Please address thsi comment, and submit. No further review will be needed, well done!
