Delft3D Sediment Model for Mississippi River Delta Site 294

Delta-X: Delft3D Sediment Model, Site 294, Terrebonne Basin, MRD, Louisiana, USA is a geospatial model output from NASA. It simulates hydrodynamics and sediment transport for an intensive site in the Mississippi River Delta during the 2021 Spring and Fall deployments. The dataset provides water velocity, depth-averaged sediment concentrations, and derived annual inorganic mass accumulation rates in netCDF format.

Use Cases

• Calibrating and validating other hydrodynamic or sediment transport models for coastal environments.
• Analyzing intra-annual variability in water levels and suspended sediment concentrations to estimate mass accumulation.
• Studying the relationship between water velocity fields and sediment concentration distributions in an estuary.

Strengths

• Model includes all required files to run the simulations, supporting reproducibility.
• Provides derived annual inorganic mass accumulation rates, adding processed metrics to raw outputs.
• Data is provided in the standard netCDF format, which is widely supported in geoscience.

Limitations

• Core dataset facts like row count, size, and specific column names are not provided by any source.
• There is a conflict in the 'last updated' date between NASA Earthdata (2021-08-28) and Data.gov (2026-03 13).
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
