Matlab Sediment Transport Model for Wax Lake Delta Accretion

Matlab scripts simulate suspended sediment transport and land accretion at the Wax Lake Delta in coastal Louisiana. The model solves advection and Exner equations, using flow data from the ANUGA hydrodynamic model based on Delta-X Spring and Fall 2021 campaigns. It was produced by NASA.

Use Cases

• Simulating suspended sediment fluxes of mud and sand as a function of space and time.
• Calculating accretion rates to model land building in a deltaic system.
• Generating annualized land accretion maps using a weighted-average formula from campaign data.
• Processing ANUGA hydrodynamic model outputs for sediment transport inputs.

Strengths

• Model is based on specific field campaigns (Delta-X Spring and Fall 2021).
• Implements physics-based equations (advection and Exner) for sediment transport.
• Produced by a authoritative organization (NASA).

Limitations

• Core model outputs (e.g., accretion maps) are archived as a separate dataset, not included here.
• Sources conflict on the last updated date (2026-03 13 vs. 2021-08-27).
• No column, row count, or direct dataset size information is provided.
