**Preface to "Modelling of Floods in Urban Areas"**

Understanding the risk of flooding in urban areas is a societal priority. However, there are significant technical challenges associated with the appropriate characterisation and representation of the numerous complex physical and hydrodynamic processes involved.

The aim of this Special Issue is thus to publish the latest advances and developments concerning the modelling of flooding in urban areas and contribute to our scientific understanding of the flooding processes and the appropriate evaluation of flood risk.

This issue contains contributions of novel methodologies including flood forecasting methods, data acquisition techniques, experimental research in urban drainage systems and sustainable drainage systems and new numerical approaches. It is addressed firstly to researchers, but practitioners will surely also find it very relevant.

In closing, we would like to acknowledge the work of the managing editor team, from the reviewers and over forty authors that submitted their work to this Special Issue.

We hope you enjoy reading it.
