Two Reviewers have provided a number of constructive comments to this paper. They both considered the study of good scientific significance and quality, while suggested a minor revision of the manuscript. The authors have already replied with a comprehensive response. Thus, I recommend submitting a revised manuscript to HESS after addressing all comments as stated in the response. In addition to the Reviewers' comments, I think it would be worth discussing more a possible limitation of the proposed method: its inability to explicitly capture the dynamics of water-related disaster risks emerging from the (still largely unexplored) feedbacks between physical and social processes (see e.g. socio-hydrology). In a rapidly changing world, risk changes significantly over time.

Two Anonymous Referees suggested a minor revision of the original manuscript (HESSD) and provided several comments. All points were all carefully addressed by the authors. This revised manuscript can therefore be accepted for publication (HESS).
