An Integrated Approach for Urban Pluvial Flood Risk Assessment at Catchment Level
Round 1
Reviewer 1 Report
Opinion of the Reviewer
A case study is presented to An Integrated Approach for Urban Pluvial Flood Risk Assessment at Catchment Level. Overall, this MS is not writing up in professional scientific way. This MS has potential to publish if it arranges in a proper way. Conventionally used techniques are adapted to Flood Risk Assessment. The presented method helps the interpretation of Flood Risk Assessment. There is no review of the relevant literature (Literature Review) to highlight what approaches have already been employed in the study area.
The suggestion about MS structure
Please arrange your paper according to this format. Include these sections which are mentioned below in order to improve the quality of the paper.
Abstract
Despite of the increasing urban pluvial flood risk, current research is focused more on fluvial flooding and coastal flooding.
Comment: it is very generic statement.
This section is fair for easy flow needs to rewrite the abstract in more comprehensive way.
Abstract should cover four main technical ingredients below:
(1) Objective definition/Key Problem – this part is not defined
(2) Methodology – this part needs to refine
(3) Results – this part is okey
(4) Conclusion – this part is okey
1. Introduction
This section is not writing up according to professional scientific way. It is suggested rewrite this section and included latest References related your work. This section not described that what is difference of your study are pervious study. It is requested to add one paragraph about your achievements and the significance of your work. Is there any improvement in methods or techniques not clear?
Figure 2. Urban pluvial flood risk assessment framework.
On what basis did you develop this figure? Please provide proper scientific justification of it?
Figure 7. Results of SoVI at catchment level (a) and the relationship between aggregated SoVI score 315 from NRI dataset and our calculations of SoVI (b).
Why r-squared 0.45???
Results and discussion
This section is fair but needs minor improvement and write in a professional scientific way. The results are calibrated with previous studies and available literature. It is suggested to integrate your results.

Reviewer 2 Report
Nowadays, the increasing urban pluvial flood risk which caused by rapid development of urbanization and global climate change, has become a hot topic for research. The paper propose an innovative metric ‘PFRI’ which generated based on multiplying EI with SoVI to assess the risk of urban flood and explore the interplay impacts of exposure and social vul- nerability. The research on Cincinnati shows that the evaluated composite flood risk has a good match with the historical flooded records and provide useful insights for urban pluvial flooding risk management.
Although the research provides a comprehensive understanding of urban pluvial flooding risk, there are some questions about the article.
1. The risk metric you Propose called PFRI is wrong in in Equation (4)ï¼›
2. There are more reasons that need to be presented to justify the metric PFRIï¼›
3. Your third objective is to explore the interplay impacts of exposure and social vulnerability(92), but in your research you only give joint action to risk (3.4). You need to have analysis between different risk components to show how one risk components affect the other.
