Abstract
In this study high resolution precipitation data are used, derived from polarimetric X-band radar at
100 m, 1 min resolution. The data are used to study the impact of different space-time resolutions
of rainfall input on urban hydrodynamic modelling response for 9 storms, in 7 urban catchments.
The results show that hydrodynamic response behaviour was highly sensitive to variations in
rainfall space-time resolution, more strongly so for changes in temporal than in spatial resolution.
Under- and overestimations of flow peaks amounted to up to 100% with respect to the original 100
m, 1 minute rainfall input.
