The rainfall distribution is one of the most important factors that affects the watershed response to a given precipitation event. This paper uses radar rainfall to simulate of the floods of the city of Hull, U.K., in June 2007. The computed flooded areas from this rainfall and a uniform one is compared against those registered by public authorities. Results show similar skills at reproducing the real event, but differences appear in the total precipitated volumes, water depths and flooded areas. It is envisaged that in urban areas and with the advent of higher resolution radars, these differences will be more important and call for further investigation.

This paper presents Itzï, a new free software for the simulation of floods. It is integrated with a geographic information system (GIS), which reduces the human time necessary for preparing the entry data and analysing the results of the simulation. Itzï uses a simplified numerical scheme that permits to obtain results faster than with other types of models using more complex equations. In this article, Itzï is tested with three cases that show its suitability to simulate urban floods.
