Run the Delta-X Sediment Model

In this tutorial, we demonstrate how to use the Inductiva API to run a series of Delft3D simulations reproducing the results of Donatelli, C., & Fagherazzi, S. (2023). Delta-X: Delft3D Sediment Model, Site 294, Terrebonne Basin, MRD, Louisiana, USA (Version 1). ORNL Distributed Active Archive Center.

The study includes the Delft3D model for Site 294 in the Terrebonne Basin along the Mississippi River Delta (MRD) in coastal Louisiana. This model is part of the NASA Delta-X mission, a five-year Earth Venture Suborbital-3 project investigating the Mississippi River Delta, which is simultaneously expanding and subsiding in different areas. The study covers the Delta-X Spring and Fall 2021 deployments, simulating water levels, flow velocities, and suspended sediment concentrations.

This case is large-scale, realistic, and scientifically validated. Unlike many research examples, the full case is publicly available via NASA’s ORNL DAAC, including forcing data, boundary conditions, bathymetry, sediment parameters, and ready-to-run Delft3D input files. The model couples hydrodynamics, sediment transport, and morphodynamics, making it an ideal example for demonstrating how Inductiva can accelerate scientific workflows, from launching simulations to efficiently generating results.

This tutorial focuses on executing the 2021 Spring deployment across multiple computational resources and is organized into three parts:

• Set up the example files
• Run the Case on Inductiva
• Evaluate the Impact of Hyper-threading
