This document reports the study with related verification tests of two expeditious methods for the characterization of flood hazards and landslide hazards that may cause damage to the national electricity transmission grid (Rete elettrica di Trasmissione Nazionale (RTN)). The methods were implemented in Python codes and subsequently tested on sample areas, verifying their good prediction capacity with respect to known hazard mappings.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[1405,1325,1324],"targets":[1317],"rapporti_tipologie":[762],"class_list":["post-195285","rapporti","type-rapporti","status-publish","hentry","tag-climate-change","tag-electrical-system","tag-electricity-network-en","targets-research","rapporti_tipologie-report-en"],"acf":{"dont_show_hompage":true,"projects":{"ID":188405,"post_author":"93","post_date":"2024-06-13 15:10:12","post_date_gmt":"2024-06-13 13:10:12","post_content":"","post_title":"Resilience and Security for Energy Systems","post_excerpt":"The goal of the project is to increase the security and resilience of the energy system in the face of greater environmental threats due to climate change, through the development of tools to support institutions and operators and the definition of an optimal set of actions to be adopted for this purpose.","post_status":"publish","comment_status":"open","ping_status":"closed","post_password":"","post_name":"resilience-and-security-for-energy-systems","to_ping":"","pinged":"","post_modified":"2024-07-02 10:30:30","post_modified_gmt":"2024-07-02 08:30:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.rse-web.it\/progetti\/resilience-and-security-for-energy-systems\/","menu_order":0,"post_type":"progetti","post_mime_type":"","comment_count":"0","filter":"raw"},"order_posts":"","dont_show_search":false,"related_posts":false,"show_on_slider":false,"single_post_data":{"titolo_spot":"","post_content":"
The study described in this document is aimed at characterizing some threats to the national energy system generated by extreme weather events, and concerns in particular the mapping of areas subject to the danger of flooding and landslides that may lead to damage to the national electricity transmission grid (Rete elettrica di Trasmissione Nazionale (RTN).<\/p>\n
<\/p>\n
To allow rapid analyses on a national scale, the study takes into consideration expeditious methods that are able to provide overall hazard assessments in a short time, also to define and prioritize macro-interventions or possibly planning-targeted studies of local in-depth analysis.<\/p>\n
<\/p>\n
As far as the mapping of the flood danger is concerned, it was decided to implement and test the Geomorphic Flood Index (GFI) methodology on a sample area of 29000 km2 of the Po basin, which is a morphological index whose value can be calibrated for different Return Times.<\/p>\n
<\/p>\n
The verification of the results with respect to the existing maps produced by the Po Basin District Authority (Autorit\u00e0 Distrettuale di Bacino del Po) has shown that it has a remarkable ability to identify quickly and with a good approximation the areas susceptible to flooding and that it also has the possibility of searching for situations of possible danger even in areas not yet mapped.<\/p>\n
<\/p>\n
Regarding the expeditious methods for estimating the hazard of rain-induced landslides, i.e., triggered by intense rainfall events, a method has been studied and implemented that refines the classic models based on slope, adding some parameters related to the stability of the slopes and evaluates their frequency by estimating the recharge time of the mobilizable material after the occurrence of an event.<\/p>\n
<\/p>\n
The verification of a test area in Valtellina (Province of Sondrio), with the map of the Italian landslide inventory (\u201cInventario dei Fenomeni Franosi in Italia\u201d, IFFI) confirms that it is a valid classifier of the areas subject to induced rainfall landslides and can discern sub-areas with the same frequency of rainfall.<\/p>\n
<\/p>\n
Furthermore, to prepare a tool for in-depth analysis at the river basin scale, in the last chapter the CRHyME geo-hydrological model updates are described, accompanied by demonstration applications in sample areas. The results obtained demonstrate the ability of the model to simulate flood or landslide events that can impact the electro-energy system.<\/p>\n
