Demonstration Case Name
Multi-hazards in Senegal (transferability case)
Dataset Name/Title
Exposure of buildings to flood - Saint-Louis, Senegal
Dataset Description
Exposure analysis of buildings
Key Methodologies
Flood water heights were simulated with the FastFloodApp. The storm was simulated as the worst-case scenario, as if three flood types, pluvial (24 mm/h in 3 hours), fluvial (54000 m3/s) and coastal (0.59 m a.s.l.), co-occurred.
Building occupancy type was determined querrying Overpass API withing building footprints.
The exposure analysis was conducted at riskchanges.org
