Reviewer 3 Report

Dear Authors,

I would like to thank you the opportunity to review the manuscript. 

Here are some notes about the submitted manuscript:

-  The manuscript presents interesting results, which are relatively well organized and systematized, but the novelty and practical applicability of this study should be highlighted more. Also, it will be useful to include some information regarding the economic impact of the work;

- The figures need to be redone. It is very difficult to understand what is described inside;

- The map of the study area should show the expanded area for the reader to understand which region of the globe is;

- Some citations are in disagreement with the norms of the journal;

- As it is a case study, I imagined that there would be more information about the physical and human characteristics of the area. You should explorate this information in your paper;

-A basic flowchart of the suggested methodology should be presented in the paper. Thus, the readers can easily follow the application procedures;

- The performance metrics part is very important for the evaluation of application results. For this aim, the performance metrics as NSE, RMSE, etc. from literature should be calculated. Then, they can be given in a table. Because of the importance of the assessment of results, these metrics are widely used in the literature, especially in the forecasting studies. The new and main papers are suggested below. They should be benefited and cited; 

- Conclusions part can be improved in the paper. Here is presented in a general concept;

- Is the used methodology in the paper valid for all areas or is there any limitation or classification for the application?

I hope I have contributed to my comments and suggestions.

Bests regards.
