CHL members attend the classroom portion of the inaugural NAUI Basic Open Water Scientific Dive SCUBA class held 15-24 July. After a grueling 80-hour program over more than 10 consecutive days, 13 ERDC divers graduated and are now members of the ERDC Open Water Scientific Dive team and the US Army Corps of Engineers diving Community of Practice. This inaugural program, the first-ever USACE-taught dive program, was directed by the Portland District Office of Dive / ROV Operations and Safety. After successful completion of academic studies, confined water and open water skill development, graduates earned diving NAUI Open Water, USACE Scientific Diver, Scientific Snorkel and Tender SCUBA endorsements as well as a Dive Office Challenge Coin.

Students Michael Winkler and Tommy Kirklin signal to each other that they are OK as they practice buddy breathing – an emergency out-of-air procedure when scuba diving.

ERDC’s Coastal Inlets Research Program, or CIRP, advances the state of knowledge and develops engineering technology for predicting the waves, current, sediment transport, and morphology change at and around inlets. Products of the CIRP improve management and design of coastal inlets through increased reliability of actions and reduction in operation and maintenance costs. The CIRP takes a variety of approaches, including developing concepts and theory for all relevant time scales, numerical simulation, field data collection, and laboratory experimentation.

Enhance Water Resources

Water resources are under increasing pressure from expected climate change and land use change, invasion by exotic species, demographic shifts, and aging structures. ERDC's Water Resources & Civil Works business area provides innovative and environmentally sustainable solutions to these and other water resource challenges.

ERDC's state-of-the-art technologies, tools, and resources provide safe and resilient communities and infrastructure, help American goods compete in the global marketplace, improve the flow of commercial navigation traffic on waterways, rebuild locks and maintain channels, reduce the risk of damage to life and property from flooding, and protect fish and plant life. Our science and technology help the Corps manage existing water resources infrastructure sustainably to meet the needs of future generations.
