Use of Seasonal Streamflow Forecasts for Flood Mitigation with Adaptive Reservoir Operation: A Case Study of the Chao Phraya River Basin, Thailand, in 2011

Round 1

Reviewer 1 Report

Comments for authors

The authors propose interesting ideas for water management and the reduction of the adverse effects of floods in the Chao Phraya River Basin (CPRB), integrating the seasonal forecast to improve the results obtained with previous methodologies. I believe that any effort made to develop or improve research related to the issue of water represents a great contribution to society. Therefore, I congratulate the authors for the effort shown. However, I consider that authors should pay close attention to the comments made by the journal's reviewers and editors, before the manuscript is considered a publishable scientific document.

General comments

I consider it important that the authors highlight the objective of the study, in the sections "Abstract" and "introduction".

You consider it appropriate that the authors highlight the advantages and disadvantages of their proposal over other works carried out, mainly that of reference [6]: “Mateo, C. M.; Hanasaki, N.; Komori, D.; Tanaka, K.; Kiguchi, M.; Champathong, A.; Sukhapunnaphan, T.; Yamazaki, D.; Oki, T. Assessing the impacts of reservoir operation to floodplain inundation by combining hydrological, reservoir management, and hydrodynamic models. Water Resources Research, 2014, 50(9), 7245–7266. “

Particular comments

At lines 97 to 98. It is not clear how the CPRB supports the local community and economy.

At line 103. When acronyms are used, it is necessary to add their meaning the first time they are used.

At lines 104 to 105. It is suggested to delete the idea “, which mean that…”. It was commented on the previous lines 103 to 104.

At line 127. Can the authors explain the use of "geological data" in research?

At line 144 (Figure 1). 1.- It is suggested to improve the quality of the figure, mainly in the texts. 2.- The graph that relates rainfall vs discharges does not have units on the secondary axis. 3.- In the figure caption, the "Rule Curves" are not mentioned.

At lines 196 to 198. It is suggested that figures (2 and 3) be placed after the text that describes or mentions them.

At lines 204 to 2015. I consider this paragraph to be very long. It should only detail the usefulness of PlanM, I consider that different ideas in this paragraph are not relevant and should be eliminated.

At lines 216 to 235. The methodology described is confusing and it is difficult to relate it to figure 3.

At lines 236 to 385. The "results" section is very long. I consider it relevant that the authors highlight and specify the main results, because it can be confusing. Since the problem is important, less should be better in this case.

At line 445. Blue o yellow line?

At lines 447 to 450. In the information in the figure, the yellow line is not mentioned.

At line 479. It is recommended to change the color of the green lines, to improve their visualization and analysis.

At lines 477 to 478. The authors mention that the prediction of the precipitation data is underestimated in relation to the observed data. How this situation affects this research and the results obtained for its application in water and flood management.

Reviewer 2 Report

The subject of your paper is interesting however after all this research you have done you have not provided any real discussion. This what you call a discussion in your paper is not a scientific discussion. Please look at any paper in any scientific journal so you will know what I mean by the real scientific discussion. You must compare your results with international literature and discuss them. Otherwise you just present a rapport not a scientific paper.

Reviewer 3 Report

How to operate reservoir to reduce flood loss is one important issue in basin management. In the manuscript, a method is updated and developed for using seasonal streamflow predictive data to support adaptive reservoir operation. the use of streamflow predictive information for adaptive reservoir operation with the aim of mitigating the 2011 flood in the CPRB is demonstrated. I think it is good innovation for reservoir management.  I think it is revised with minor revision.

Some comments:

1, in 2011, the runoff is the catastrophic flooding occurred in Thailand. The case of 2011 is an extremely typical year flood, whether this case has a universal application for the basin? For example, reservoir operation of general flood.

2,in the title and abstract, give Innovative title and points of innovation to improve the research innovation.

3,the The resolution of these precipitation data is 1°in both latitude and longitude. I think it is lower for the CPRB basin,which is 158,000 km2.if you use 1-10km,maybe get better results.

4, in the manuscript,  H08 model is used, how about principle and its applicability of the model in the basin?

5, in figure(a)-(c), all legends could be put together. Because every figures have same legends.

the figure 11-12 are same as.

Dear Authors,

I am sorry to say but still in your paper there is no real scientific discussion of your results. Please take a look into a few international papers and you will see what I mean by the discussion:
