Area of hazard of the catchment areas of Alzone and Agosta — municipalities of Grosseto-Prugna, Albitreccia and Pietrosella
Description
Area exposed to one or more hazards represented on the map of hazards used for risk analysis of the catchment areas of Alzone and Agosta in the municipalities of Grosseto-Prugna, Albitreccia and Pietrosella.
The hazard map is the result of the 2011 ANTEA flood risk study which assessed the flood risk in these watersheds.
The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity.
All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure).
Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards.
