Washover Morphometry: Lidar and Literature Measurements

New Jersey, USA, coastline data includes lidar-derived topographic change measurements following Hurricane Sandy (2012) and a compilation of 35 washover measurements from six published studies. The dataset provides quantitative metrics like deposit width, intrusion length, area, and volume for coastal overwash deposits. It is intended for analyzing the geomorphic impact of storms and validating models of coastal sediment transport.

Use Cases

• Quantifying storm-induced sediment deposition based on lidar-derived deposit volume and area.
• Comparing washover dimensions across different storm events using the compiled literature examples.
• Modeling coastal vulnerability by analyzing relationships between morphometric features like intrusion length and built fraction.
• Validating remote sensing analysis techniques using the provided pre- and post-storm geospatial data layers.

Strengths

• Includes a specific compilation of 35 measurements from six peer-reviewed studies, providing a literature-based benchmark.
• Derived from authoritative lidar sources (NOAA Digital Coast, USGS EAARL-B) for a major storm event (Hurricane Sandy, 2012).
• Cross-platform presence on PapersWithCode signals recognized utility in the research community.

Limitations

• Key metadata such as row counts, file sizes, and specific update dates are missing from all source descriptions.
• The dataset's temporal coverage is unclear beyond the focal event of Hurricane Sandy (2012).
• Documentation gaps exist regarding the exact processing steps for the geospatial layers beyond the described QGIS workflow.
