Northern Ireland Coastal LiDAR Survey After Storm Events in 2022

Fugro commissioned a LiDAR survey of soft sedimentary coastlines on the north coast of Northern Ireland in March 2022 following storms Dudley, Eunice, and Franklin. The survey covered Curran Strand, Portrush East Strand, Portstewart Strand, and Downhill Beach to Magilligan to assess storm damage relative to a 2021 baseline. A repeat survey from White Rocks to Magilligan was conducted in September 2022 to measure coastline recovery.

Use Cases

• Quantifying coastal erosion based on LiDAR-derived topographic change data.
• Monitoring beach recovery patterns based on repeat surveys conducted in March and September 2022.
• Analyzing storm impact on specific beaches mentioned in the description, such as Portstewart Strand.
• Creating visualizations of coastline change based on orthophotography collected during the surveys.

Strengths

• Data is directly comparable between surveys, enabling precise change quantification.
• Survey specifications are detailed, including a 0.5m resolution and collection from the intertidal area to 10m inland.
• Survey timing constraints are explicitly documented, providing context for data collection conditions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
