Delft3D Sediment Model for Mississippi River Delta Site 322

A Delft3D model simulates hydrodynamics and sediment transport for intensive site 322 in the Terrebonne Basin, Mississippi River Delta. The dataset includes all required simulation files and outputs water velocity, depth-averaged sediment concentrations, and annual inorganic mass accumulation rates for the Delta-X Spring and Fall deployments in 2021. Data is provided by NASA in netCDF and ENVI formats.

Use Cases

• Analyzing intra-annual variability in water levels and suspended sediment concentrations from model outputs.
• Calibrating or validating other hydrodynamic or sediment transport models for similar coastal environments.
• Studying annual inorganic mass accumulation rates to understand delta growth and subsidence.
• Investigating the relationship between water velocity and sediment concentration patterns in a fluvial-marine transition zone.

Strengths

• Model includes all files required to run the simulations, providing a complete workflow.
• Outputs cover two distinct seasonal deployments (Spring and Fall 2021), capturing intra-annual variability.
• Data is provided in standard scientific formats (netCDF, ENVI) suitable for analysis and visualization.

Limitations

• Core dataset metrics like row count, column names, and exact file size are unspecified across all sources.
• There is a conflict in the 'last updated' metadata: Data.gov lists 2026-03-13, while NASA Earthdata lists 2021-08 28.
