Modelling Sea Level Rise and Storm Surge Risk for Coastal Resilience

About

A coastal region comprising multiple cities required a strategic assessment of rising sea levels and intensifying storm activity. Facing increasingly severe weather events driven by climate change, the region sought to understand the vulnerability of critical infrastructure and to develop longterm resilience strategies. Geospatial Intelligence was engaged to conduct a comprehensive analysis using Earth Observation data to model stormsurge scenarios and identify highrisk coastal zones. 

The Challenge

The coastal cities face escalating climateinduced threats that endanger infrastructure, communities, and longterm urban resilience. The primary risks identified included: 

  • SEALEVEL RISE

    Rising ocean levels are placing growing pressure on coastal settlements, increasing the likelihood of inundation and longterm land loss. 

  • EXTREME STORM SURGES

    Severe weather events are becoming more intense and frequent, with 5m and 10stormsurge scenarios projected to cause widespread damage if unmitigated. 

  • INFRASTRUCTURE EXPOSURE

    Transport corridors, utilities and essential community assets are increasingly vulnerable as storm events become less predictable and more destructive. 

Through this project, the cities gained high resolution modelling and scenario-based insights, enabling them to proactively plan for future coastal hazards. Our analysis now underpins improved emergency planning, infrastructure investment, and strategic climate adaptation.
