The authors are invited to revise the manuscript following the replies they have provided to the reviewer comments.
Just a note with respect to AC1: at bullets 2 and 5 it is suggested to add information in the Conclusion section; I believe these fit better in a Recommendations and Discussion section, respectively (the latter supported by references to the literature)

The authors have adequately addressed the reviewers' comments and implemented corresponding revisions of the manuscript.
Before the manuscript can be accepted for publication, I would like to ask the authors to better highlight the relevance of their work for the themes of the HESS journal. Their work is strongly hydraulics-oriented and a connection to the journal's themes, for instance micro-scale physical processes, spatial and temporal characteristics of water resources, needs to be made more clear (see HESS website for more details about the journal scope and themes). This will also help to enhance discoverability of the paper for the hydrology community working on urban flood prediction. This can be relatively easily achieved by making minor changes to title, abstract, keywords and some of the phrasings in introduction and conclusions.
