Coastal and Ocean Modeling
Many of our researchers specialize in state-of-the-art oceanographic, hydrodynamic, water quality, and ecosystem modeling to solve water and natural resource issues in a host of aquatic systems. We use comprehensive numerical modeling to build scientific understanding and support decision-making for all aspects of the water hydrologic cycle. This includes everything from rainfall and runoff from watersheds to flows in small streams to distributed flows in larger river systems to circulation in wetlands, estuaries, and coastal waters. Our modeling capabilities span from simple one-dimensional (1-D) flow and effluent dilution models to complex three-dimensional (3-D) computational fluid dynamic (CFD), hydrodynamic, fate and transport, and comprehensive water quality models.

International Collaboration and Knowledge Management
PNNL developed Tethys, a global, open-access database that facilitates the exchange of information and data on the environmental effects of both wind and marine renewable energy technologies. Additionally, Tethys Engineering was developed as a sister program to Tethys and provides an archive for the technical and engineering development of MRE devices. These Tethys efforts were developed to support the U.S. Department of Energy Water Power Technologies Office and the Wind Energy Technologies Office, and function as platforms for the International Energy Agency Ocean Energy System’s OES-Environmental Initiative. The Tethys knowledge bases cultivate collaborative research spaces for project developers, regulatory agencies, stakeholders, and researchers from around the world to access and share data, connect with the research community, and propel the industry forward. Creators and users of Tethys have a common goal: to detangle and clarify the complex environmental issues associated with MRE and wind energy and engineering challenges associated with MRE through the exchange of data and information.
