How Airports Protect Against Flooding: Strategies for Safety and Resilience

As climate change heightens flooding threats, airports worldwide are implementing innovative strategies to safeguard against water damage and operational disruptions. With many facilities built near coastlines or low-lying areas, these flood-prevention measures have become essential for airport resilience.

Elevated Infrastructure and Enhanced Drainage

Raising critical structures, like runways and terminals, helps airports combat rising water levels. Hong Kong International Airport and New York’s LaGuardia have both elevated key areas to shield against storm surges. Additionally, robust drainage systems, including large pipes and retention basins, are used to manage excess water during heavy rain, as seen at Tokyo’s Haneda Airport.

Protective Barriers and Permeable Surfaces

At higher-risk locations, flood barriers and gates provide a physical shield against incoming waters. Amsterdam Schiphol utilizes floodgates to prevent water intrusion, while permeable surfaces, like those at Singapore’s Changi Airport, absorb rainwater and reduce runoff.

Real-Time Monitoring Systems

Airports like Miami International employ real-time flood monitoring to anticipate and respond to rising water levels, allowing staff to take timely actions and minimize disruptions.

Through a mix of elevated infrastructure, protective barriers, and real-time monitoring, airports are bolstering resilience against floods, ensuring safer, more reliable travel even as environmental risks grow.
