261 - Landslide Pipe Criticality Analysis Linking Hazard and Social Vulnerability Data

Resilience analysis of critical infrastructure is inherently complex and requires the integration of diverse geospatial data and disparate models in a cohesive analysis to produce meaningful decision support. Recent updates to the Water Network Tool for Resilience (WNTR) allow incorporation of up-to-date geospatial data describing the water system, hazards, and surrounding community into a resilience analysis. In this presentation, we will show a resilience analysis of the drinking water system in a U.S. city which integrates the water distribution network model, landslide susceptibility, social vulnerability, and emergency service locations. Results demonstrate that pipes can be prioritized for mitigation based on water shortage and vulnerable populations that are affected. The methods can be adopted for general use and are available as part of the WNTR software.
