Channel Bathymetry Survey of the Wax Lake Delta, 2016

October 16-20, 2016, bathymetric surveys captured water depths and surface elevations in the main channel of Louisiana's Wax Lake Delta. The data consists of continuous 1 Hz in-situ measurements integrated with GNSS location data, collected during the Pre-Delta-X Campaign. These measurements were used to generate a merged digital elevation model (DEM) for the delta's channels.

Use Cases

• Generating merged digital elevation models (DEMs) for wetland channels using bathymetry and GNSS elevation data.
• Analyzing channel morphology and water depth variations across the five-day survey period.
• Studying sediment transport and deltaic landform development in the Mississippi River Delta floodplain.
• Calibrating and validating remote sensing data for coastal bathymetry.

Strengths

• Provides high-temporal-resolution (1 Hz) continuous bathymetric measurements.
• Data is integrated with precise GNSS location and elevation data for accurate georeferencing.
• Supports a specific scientific campaign (Pre-Delta-X) focused on delta processes.

Limitations

• Specific row count, file size, and detailed column names are unavailable across all sources.
• Sources disagree on the last updated date, reporting either 2016-10-20 or 2026-03-12.
