The present study defines an original methodology for diagnosing the vulnerability of infrastructure to climatic events. Against existing approaches, this methodology increases the objectivity in the assessment and weighting of the aspects involved in a multicriteria procedure. In addition, it includes the automation and digitalization of the process.
For this purpose, concepts extracted from the MIVES methodology (Integrated Value Model for Sustainable Evaluation) are used, especially the Hierarchical Analytical Procedure, combined with the GIS (Geographical Information System) support of infrastructure and its environment information (geo-referenced spatial information with semantic information associated).
The procedure has been particularized for the case of road flooding. For its validation and optimization, it has been applied on two real cases: the A-92 between Seville and Almeria and the variant to the N-435 between the towns of Beas and Trigueros.
With all this, a procedure has been defined and validated to obtain a unique measurement / comparison index of the degree of vulnerability to flooding of the different units of analysis or sections into which the road infrastructure is previously divided.
