CHL Products and Services

Charged with operating more than 13,000 miles of coastal navigation channels, the U.S. Army Corps of Engineers needs robust decision-support technologies to better manage its vast portfolio. ERDC’s Coastal Inlets Research Program infuses these technologies into the hands of practitioners to ensure mission success. The program develops a robust suite of engineering technology focused on Coastal Modeling, Inlet Engineering, Inlet Geomorphic Evolution and Coastal Navigation Portfolio Management. Its tools support the Corps of Engineers from engineers and scientists working at the project scale to regional- and national-level business line managers overseeing the Navigation Operations and Maintenance Program. Its modeling techniques accelerate the prediction of processes and cut costs by several orders of magnitude.
Beach-fx is a comprehensive innovative modeling tool and analytical framework for evaluating the physical performance and economic benefits and costs of shore protection projects.
