Flood Risk Management Plan - PGRA - Hazards - last update

Delimitation of areas affected by flood events for three flood scenarios: frequent (TR 20-50 years), infrequent (TR 100-200 years) and rare (TR up to 500 years). It represents the most recent update of the hazard, realigned with the picture of the failure of Draft 2 of the IAP and with the updated river bands. The data are organised into three distinct layers according to the type of water element:- Main lattice (RP) – areas with different hazards mainly related to watercourses with river bands;- Secondary, hilly and mountainous lattice (RSCM), mainly related to mountainous hilly watercourses at the bottom of the valley or secondary, along the slopes and in cone, lowland lattice related to secondary watercourses, irrigation canals (RSP);- Lake environment – flooded areas due to lake level rise (ACL).
