Post-Storm Coastal Recovery LiDAR Surveys of Northern Ireland

Fugro's 2022 LiDAR surveys captured the impact of three successive storms and subsequent recovery along the soft sediment north coast of Northern Ireland. Data was collected at 0.5-meter resolution from the intertidal zone to 10 meters inland under restrictive tidal and weather conditions. This dataset provides a direct comparison to a 2021 baseline survey, enabling precise measurement of coastal change.

Use Cases

• Quantifying beach volume loss based on pre- and post-storm digital surface models.
• Assessing natural recovery rates of soft sediment coastlines between March and September 2022.
• Informing coastal management strategies for areas like Curran Strand and Portstewart Strand.
• Validating coastal erosion models with high-resolution topographic change data.

Strengths

• Provides temporally specific data from two surveys in March and September 2022, enabling change detection.
• High spatial resolution of 0.5 meters allows for detailed geomorphic analysis.
• Dataset is cross-referenced with a 2021 baseline survey from the Northern Ireland 3-Dimensional Coastal Survey.

Limitations

• Critical metadata such as column names, row counts, and file sizes are not provided by any source.
• The survey's restrictive acquisition window (2 hours around low tide, daylight only) limits temporal coverage.
• Spatial coverage is limited to specific soft sediment areas on the north coast, not the entire coastline.
