Abstract. Flash floods are caused by intense rainfall events and represent an insufficiently understood phenomenon in Germany. The understanding of damage caused by flash floods requires ex-post collection of relevant but yet sparsely available information for further research. Thus, on-site data collection was carried out after the flash flood event on 29 May 2016 in Braunsbach, Germany, using open source software as helpful and efficient tool for data acquisition and evaluation. The post-hoc analysis links process intensities to damage and reveals differences in damage driving factors of flash floods compared to riverine floods, indicating that also risk patterns vary among different flood types.

Short summary
The fash flood in Braunsbach, Germany, in May 2016 was a severe and – in the recent past – rather unfamiliar event which caused high monetary losses and heavy damage at buildings. Between June 6th and June 9th we investigated all affected houses and conducted a damage assessment to gain insights into the damage driving factors of those events. We conclude that the damage driving factors are complex and also differ partly from those of riverine floods, pointing out the need for further research.
