The manuscript has received two reviews. While the CRB method is a widely applied method, both reviewers agree that the manuscript is an important advance in formalizing the application of the CRB method and addresses important outstanding questions about its applicability.

I find that, in general, the authors proposed revisions address the reviewer comments. I am, therefore, recommending that the authors now implement their proposed revisions. I would also add there are several author comments that need a more complete response and associated changes in the revised paper. This applies to RC1, comments 1-3 and RC2, comments 2.2 and 2.4, where additional text should be added to the manuscript to address these comments. Even if additional analysis is not conducted, they are important points and should be at least noted. Consider using the author responses as a basis for the additional text in the revision.

The revision will likely be sent for review before a final decision is made. I look forward to the revised paper and thank you for this submission to HESS.

The discussion paper had received two reviews, one of which suggested minor revisions and one of which suggested major revisions. The revised discussion paper was sent to the reviewer (Reviewer #2) who had suggested major revisions to ensure the review comments were fully incorporated.

Reviewer #2 has now returned their review of the revised discussion paper. You will see in their assessment that the initial review comments have been addressed; however, there are a number of additional minor but important comments to consider before the discussion paper can be accepted in HESS. If these comments are fully addressed, I concur with the assessment that the paper will not need to be sent for review again. I hope that you will be able to make these changes.

The revised manuscript had received a decision of Minor Revision and the authors have fully addressed the reviewer comments at this stage.

In my final review of the manuscript, I noticed that some of the tables and figures (Table 1, Figure 6, Figure 8 (no units on the x-axis) and Figure 10) do not express the units in SI units, as required by the HESS guidelines (https://www.hydrology-and-earth-system-sciences.net/submission.html#math). I am very sorry that I did not catch this sooner. Once these changes are made, the manuscript is ready for publication in HESS.
