Delft3D Sediment Model for Mississippi River Delta Site 399

Louisiana's Terrebonne Basin hosts this Delft3D model dataset for intensive site 399 along the Mississippi River Delta. It contains simulations for the Delta-X Spring and Fall deployments in 2021, providing outputs for hydrodynamics and sediment transport. The dataset includes all necessary files to run the simulations and is provided by ORNL_CLOUD.

Use Cases

• Analyzing water velocity patterns during the 2021 Delta-X deployments.
• Modeling depth-averaged sediment concentration for coastal Louisiana.
• Calculating annual inorganic mass accumulation rates using provided model outputs.
• Studying intra-annual variability in water levels and suspended sediment concentrations.

Strengths

• Model includes both Spring and Fall 2021 deployments, providing seasonal comparison.
• Dataset contains all files required to run the Delft3D simulations, ensuring reproducibility.
• Outputs include both hydrodynamic (water velocity) and sedimentological (concentration, mass accumulation) variables.

Limitations

• Specific row counts, column names, and dataset size are unknown across all sources.
• Conflicting last updated dates exist: one source reports 2026-03-13, another reports 2021-08-28.
• License is specified as 'other-license-specified', requiring users to investigate terms.
