Flooding events provide valuable opportunities to collect empirical data on the processes that drive building damage. In the aftermath of Ex-Tropical Cyclone Gabrielle, post-event flood damage surveys were conducted across the Hawke’s Bay and Tairāwhiti regions. In this presentation we will share damage observations and data for over 1,000 buildings, capturing flood hazard intensities, building characteristics, and damage to individual building components. We identify the key factors contributing to building damage during the cyclone and offer insights into how this damage data can inform future flood risk assessments.
