Assessing flash flood control using Universal Risk Matrix

ONLINE FIRST (pre-proof)

Abstract

Flash floods have a significant impact on both natural and economic environments, making it essential to analyze their causes and develop mitigation strategies. This study evaluated flood mitigation in a selected area using a risk map created through the application of a risk assessment framework (RAF) and also the Analytical Hierarchy Process (AHP) method, while risk levels were assessed with the Universal Matrix of Risk Analysis (UMRA). No similar mapping approach and risk assessment had been used in the region before. On the result map identified the Cseres Valley as a high-risk area. Analysis showed that implementing the proposed mitigation measures could reduce the negative effects of flash floods by about 65%, demonstrating the potential effectiveness of targeted flood protection strategies.
