The authors analyze the impact of the spatial variability of rainfall and of the spatial arrangement of NBS on hydrological outputs of NBS scenarios at the urban catchment scale

The manuscript has been revised by two reviewers who suggested (overall) moderate revisions, mainly related to the inclusion in the manuscript of additional relevant details (such as the space-time resolution, model parameters, model performance,…).
The authors provided a detailed answer to the reviewers’ comments, highlighting the main changes they envision in the manuscript.


My main concern regards the application of the Surface-Subsurface Model (Multi-Hydro model). In their analysis the authors did not model the infiltration process, in order to simply the procedure. Although I understand the authors’ attempt to simplify the problem, the infiltration process can be extremely important for the problem considered and cannot be neglected. One aspect that the authors should consider during the revision of their work is to further elucidate this aspect.

The Authors have seriously taken in consideration the main comments of the reviews and provided a stronger revised manuscript.
