Short summary

This paper evaluates the effect of surge water level reduction due to land surface characteristics when assessing flood impacts at global scales. Our results show that uncertainties due to not accounting for water attenuation are of similar magnitude to the uncertainties regarding the total amount of sea-level rise expected by 2100, thus highlighting the need for better understanding of the spatial and temporal variation of water levels across floodplains.
