This dataset delineates hazard levels for watercourse-related risks in the canton of Geneva, covering flooding and erosion. Hazard degrees, indexed from 1 to 9, result from combining intensity classes with probability classes for each danger type. Where an area is exposed to more than one type of hazard, the mapping accounts for the combined effect. The data is maintained by the Système d'information du territoire genevois (Geneva territorial information system) and supports risk assessment and land-use planning along rivers and streams.Les degrés de danger sont délimités pour chaque type de danger (inondation et érosion). La combinaison des classes d'intensité avec les classes de probabilité permettent de décrire les degrés de danger (indexés de 1 à 9). Dans le cas où une surface est menacée par plusieurs types de danger, c'est l…
