Urban Flood Resilience: Lessons from the New Orleans Katrina Disaster

As climate change accelerates, coastal cities face unprecedented risks from extreme weather events. Understanding the systemic failures and recovery efforts of past disasters is essential for designing resilient urban futures. This text-only course guides you through a deep analysis of the New Orleans flooding following Hurricane Katrina, examining how infrastructure, governance, and urban planning intersect during a crisis. You will learn to evaluate vulnerability and design modern adaptation frameworks for vulnerable cities. What you will learn: Understand the foundational concepts of urban hydrology, flood plains, and defensive civil engineering; Analyze the engineering and policy decisions that contributed to the breaching of the New Orleans levee system; Evaluate the socio-economic impacts of natural disasters and the importance of environmental justice in recovery planning; Explore modern climate adaptation strategies, including nature-based solutions, sponge-city concepts, and green infrastructure; Apply risk-assessment frameworks to identify vulnerabilities in contemporary coastal urban areas. You will begin with core definitions of hydrology and urban planning before diving into the historical timeline of the Katrina disaster. The course then transitions to modern resilience strategies, offering written case-study analyses and practical design exercises. Designed for beginners interested in urban studies, environmental policy, or civil engineering, this course requires no prior technical background.
