Short Summary

This paper develops a quantitative methodology to assess the regional economic vulnerability of urban areas to flash floods, utilizing 118 economic variables and statistical methods to construct an Integrated Economic Vulnerability Index (IEVI) and identify spatial patterns in Castilla y León, Spain.

Objective

• To develop a quantitative methodology for the assessment of regional economic vulnerability to flash floods.
• To analyze the economic vulnerability of urban areas to flash floods by estimating an Integrated Economic Vulnerability Index (IEVI) and identifying spatial patterns of vulnerability.

Study Configuration

• Spatial Scale: Castilla y León, northwest Spain; 94,223 km²
• Temporal Scale: Current (data up to 2018, year of publication)

Methodology and Data

• Models used: Hierarchical segmentation analysis, Principal Components Analysis (PCA), Tolerance statistic (for weighting IEVI), Quintiles (for mapping vulnerability), Latent Class Cluster Analysis.
• Data sources: 118 economic variables (implied from official statistical databases).

Main Results

• An Integrated Economic Vulnerability Index (IEVI) was successfully developed.
• IEVI scores demonstrate high spatial variability across the study area.
• The relationships among different vulnerability factors exhibit a high degree of complexity.
• The methodology effectively identifies spatial patterns of economic vulnerability, which can inform targeted risk management strategies.

Contributions

• Provides a novel and comprehensive quantitative methodology for assessing economic vulnerability specifically to flash floods, addressing a gap in existing literature which often focuses on general flood vulnerability.
• Develops an Integrated Economic Vulnerability Index (IEVI) based on a large and diverse set of economic variables (118).
• Enables the identification of spatial patterns of vulnerability, facilitating the design of suitable vulnerability reduction strategies and improving the efficiency of flood risk management plans and policies.
