Multi Scale CVI
• Multi Scale CVI, A Cooper and S. McLaughlin, (University of Ulster, N. Ireland)
• Work in different scales– National level– Regional level– Local level
• Different parameters at different scale

Multi Scale CVI
Vulnerability = f coastal characteristics + coastal forcing + socio-economic
