The manuscript describes the effect of both the space variability of rainfall and the (spatial) implementation of different nature-based solutions (NBS) on the hydrological response of an urban catchment southwest of Paris. This is done for three rainfall events using a physically-based, spatially distributed hydrological model, which was derived on a 10-m spatial and 3-min temporal resolution. The authors clearly show the impact of taking into account, or not, the spatial variability of
