Reviewer 3 Report
The study simulates long-term streamflow and characterize baseline drought events in two most dammed rivers, the Sesan and Srepok Rivers in the Mekong River Basin from 2001 to 2019, to understand drought impacts for river management and sustainable development of hydropower. I found the paper interesting and the authors presented their findings well. I believe the paper will be a good addition to Sustainability journal. However, the manuscript requires Major modifications before publication. Please find more details in the second comment below.
Major Issues:
- The authors didn’t summarise their study main objectives in the Introduction section, which is usually be the last paragraph in the Introduction.
- Introduction is too short. Authors needs to put more efforts in the literature review.
- Longer time -period is preferred to do such simulations especially when drought analysis is included, for example: 30 years and longer.
- Discussion section needs to be modified and separated from the results section.
- Conclusion Section: needs to be modified and highlight the main outputs of the study.
Minor Issues:
- Line 24: The authors should define the “3S” at first occurred in the manuscript and define the study area more clearly “like in Vietnam”.
- Lines 258-270: please move the first paragraph in the conclusion section to the Discussion section.

Reviewer 4 Report
This manuscript reports a detailed study of hydrology and its link to drought analysis in Sesan and Srepok. In general, the authors have considered most of the aspects and presented the data in a good form. I would recommend a minor revision before acceptance for publication.
More specific comments:
Table 2. The authors should provide reasons why the classification in Hao, et al, is suitable in the case of this study.
The numbers and percentages must be supported with SD. In addition, the differences and similarities should be done with statistical analysis, such p-test.
