Dynamic Flood Risk Assessment for Transportation Infrastructure in Fresno, CA
This project aims to assess flood risks to transportation infrastructure in Fresno County using high-resolution Airborne Laser Scanning (ALS) and Geographic Information Systems (GIS). The study will identify vulnerable roadways, bridges, and drainage systems, simulate flood scenarios, and propose actionable mitigation strategies. By integrating ALS data with advanced hydrological and hydraulic models, the project will deliver a GIS-based tool to enhance flood resilience and transportation planning.

Dates:
March 2025 to March 2026
Implementation of Research Outcomes:
This research will produce
• GIS-based flood risk maps to prioritize infrastructure upgrades.
• Actionable recommendations for improving drainage and road design.
• A decision-making tool for local agencies to support resilient and sustainable transportation planning.
• The results will not only benefit Fresno County but also provide a model for addressing transportation flood risks in similar regions.
Impacts/Benefits of Implementation:
This project enhances flood resilience in Fresno by identifying vulnerable transportation infrastructure using high-resolution ALS and GIS-based modeling. It provides flood risk maps and a decision-support tool to help local agencies plan upgrades and emergency responses. The approach supports SB-1 goals and offers a scalable model for other flood-prone regions.
