Repeatedly, dynamic flooding causes high loss in many mountain regions all over the world. Dynamic flooding is a group of hazard processes includingfluvial sediment transport, debris floods, and debris flows, as well as to some extent flash flood hazards if these are related to mountaincatchments. Regardless of the magnitude and frequency, the consequences of dynamic flooding are strongly connected to the vulnerability of elements at risk, such as people, buildings and infrastructure. Several methods to assess physical vulnerability of buildings towards these processesare available. The plethora of methods andapproaches, however, makes a comparison between different case studies challenging. Assessment methodscan be classified inthree categories: vulnerability matrices, vulnerability curves and vulnerability indices. We provide a short review of these methods and discuss theirdominance in the scientific debate onmountain hazard risk managementover the last decade, giving an emphasis to vulnerability curves. Furthermore, challenges in vulnerability assessment including data requirements, uncertainties, and needs for improved event documentation are outlined. |
