Concern Condition for Applying Optimization Techniques with Reservoir Simulation Model for Searching Optimal Rule Curves

Round 1

Reviewer 1 Report

This paper offers a thorough review of optimization techniques used in reservoir simulation-optimization models to determine optimal rule curves. And the paper also discusses the optimal conditions for future situations. On the whole, the theme of this paper is quite meaningful. However, it seems that this review article only summarizes various parts, including inflow data, objective function, smoothing function, downstream water demand, initial reservoir conditions, and evaluation scenarios, etc. but lacks reasonable comments, current situation analysis and induction, and does not point out the current situation, critical problems or questions and also development trend. So, it is suggested to further modify and improve.

Some comments are as follows:

1.      The Abstract need to be rewrite.

2.       All figures need to be further normalized. Further text explanation is required under each picture title.

Dear Editor,

We really appreciate the reviewers' comments, which are very detailed and very helpful in improving our manuscript. We have made a minor revision to our manuscript. We have improved our manuscript following reviewers' comments. All of the changes have been modified in the revised manuscript. We have addressed all of the comments which are shown below for each one, in which the reviewer’s comments are in black text and authors’ responses are in red text. Please find the attached file of response to reviewers. In addition, the author has also edited the Similarity Rate Report according to the sentence that the editor has notified, and the corrected one is green.

Reviewer 2 Report

This work presents a review on optimization algorithms for searching optimal rule curves. In particular, this work collocates itself in the family of papers related to optimization algorithms for reservoir management based on rule curves. However, this work is able to give a new insight of the problem with a specific attention to future scenarios and forecasting. I strongly recommend its publication on WATER after considering the following comments.

1) Could the author better specify the meaning of “ future situations”?

2) Line 66, regarding “These include particle swarm optimization (PSO)….” Please add, if deemed appropriate, the following reference: “Short-term hydropower optimization driven by innovative time-adapting econometric model” and “Smpso: A new PSO-based metaheuristic for multi-objective optimization”

3) What about hydropower optimization? See for example “Design of optimal operating rule curves for hydropower multi-reservoir systems by an influential optimization method”, “Optimization of fuzzified hedging rules for multipurpose and multireservoir systems” and “Detailed simulation of storage hydropower systems in large Alpine watersheds”. Please add a paragraph about hydropower in the introduction and mention explicitly that is not the aim of the work.

There are some errors regarding indentation and the usage of capital letters after equations. See for example lines 85 and 86.

Round 2

Reviewer 1 Report

The article has been improved a lot after revision. But there are still some minor problems that need further revision as following:

1.      Figure 2, 3, 11 and 12 are not clear, suggested to change the color of the lines for distinction and clarity.

2.      Please check whether you want a period “.” at the end of the headings of graphs and tables.
