Reviewer 3 Report
1.Since the approaches shown in this study are used in various fields, please describe the novelty and innovation of the proposed approach. How does it become superior to other techniques?
2.The factors including water quality type, chemical condition, biological condition, water source type and so on, ought to be presented in the description of the study area and included in the prediction models. The discussion should be conducted with the background of these factors due to their internal relationship with sewer condition.
3.The predictions of KNN, SVR, MLP, Adaboost, GB, and HGB were deteriorated from those of the original damage score dataset. What are the reasons? Please add more discussion.
4.Please show the advantage and disadvantage of ten types of model.
5.Author adopted several models from the literature to predict damage score. Author should discuss why a model fitted the data well, and the other ones didn't. They may look into the underlying assumptions of those models. Such discussion will add more values to this study.
6.Please discuss the limitations of practical application for proposed techniques.
7.Please describe how to apply the results in environmental management.
