Louisiana Coastline Interactive Portal Project
In partnership with the Coastal Protection and Restoration Authority (CPRA) of Louisiana, PSC has developed an interactive public portal showing the Louisiana coastline as it is predicted to change over the next 50 years.
Seeing into the future
The team utilized PSC’s Bridges-2 (and before that, Bridges) to run simulations to assess the water landscape of Louisiana, taking advantage of the large storage capabilities of those systems. The data collected about the water basin included individual metrics such as area habitat, salinity, and water elevation, and risk-related factors like hurricanes, wave heights, flood depths, and storm events.
The data collected and run on the simulations also fed into a risk assessment, which informed the CPRA’s 2023 Master Plan, a vital document for state decision-making and funding allocations.
In order to translate the information collected into a publicly accessible format for lawmakers, decision-makers, and anyone interested in learning more about their local environment, CPRA turned to PSC staffers Juan Puerto and Matt Yoder to create the public portal on Bridges-2.
The portal is hosted on a virtual machine on Bridges-2, using the capacity of Bridges-2’s Ocean file system to avoid any massive data transfers from local drives. It is publicly accessible and interactive – visitors can see the land change and vegetation type of the Louisiana water basin at its current state, and as it will evolve over the next 50 years, in 10 year increments.
More features will be added to the portal in the future, such as new variables and a walkthrough feature that gives even more detail about what is shown on the map.
This research was honored with the Editor’s Choice Award for Best Use of HPC in Response to Societal Plights, at the 2021 International Conference for High Performance Computing, Networking, Storage and Analysis (SC21).

What is the Coastal Master Plan?
- Prioritizes the most cost-effective solutions to reduce storm surge based flood risk and restore and maintain coastal wetlands for the next 50 years
- Built on world class science and engineering
- Illustrates how the coast is going to change
- Required by law to be updated every six years
- Incorporates extensive public input and review
- Advances a comprehensive and integrated approach to protection and restoration
- Identifies investments that will pay off now and for future generations
