The Coastal Risk Assessment Framework (CRAF) answers the question where areas of increased coastal risk (so-called hotspots) are located. The CRAF takes a two-step approach to select these hotspots:
Phase 1: Identification of potential hotspots
Along the coast, potential hotspots, i.e. sectors with a high potential exposure, are determined for different hazard indicators (e.g. wave overtopping, flooding and coastal erosion) and for different exposure indicators (land use, social, transport, utilities and economic activities). Results are presented in the form of a coastal exposure index, using the Coastal Vulnerability Indicator Library [T1] and [D1]. The results of the CRAF phase 1 are visualized in the web-based viewer [T2].
Phase 2: Hotspots risk analysis and selection
The potential hotspots are further analysed to Identify of the most critical hotspots based on current and future climate scenarios using more advanced hazard and impact assessment models. The models used are:
- XBeach (1D) [T3] a morphodynamic model to compute hazards of overtopping and erosion for selected return-period storms
- LISFLOOD [T5]: an inundation model to compute the hazards flood depth and velocities based on the computed overtopping.
- INDRA (Integrated DisRuption Assessment) to compute the impacts of various categories and score the hotspots using a Multi-Criteria Analysis (MCA).
