Innovative Vulnerability and Risk Assessment of Urban Areas against Flood Events: Prognosis of Structural Damage with a New Approach Considering Flow Velocity

The floods in 2002 and 2013, as well the recent flood of 2021, caused billions Euros worth property damage Germany. aim project Innovative Vulnerability Risk Assessment Urban Areas against Flood Events (INNOVARU) involved development a practicable model that enables realistic statements for residential building stock. In addition to determination local risks, it also takes into account vulnerability individual buildings allows prognosis structural damage. this paper, we discuss an improved method due impact. Detailed correlations between inundation level flow velocities depending on types, number storeys, are considered. Because reliable data from events with high were not available, innovative approach was adopted cover wide range velocities. proposed combines comprehensive collected after Germany 2011 Tohoku earthquake tsunami Japan. application developed methods reinterpretation by August six study areas Free State Saxony.
