Vulnerabilidad de las infraestructuras frente a eventos climáticos. Inundación de carreteras

Abstract

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.
