This dataset contains the full set of training materials used in a marine hydrokinetic (MHK) modeling workshop conducted by Sandia National Laboratories for the University of Alaska Fairbanks, funded through the U.S. Department of Energy's TEAMER program. The workshop focused on the use of the SNL-Delft3D-CEC and SNL-SWAN modeling tools, which simulate the hydrodynamic and environmental impacts of current and wave energy converters, respectively. The materials were developed to support the evaluation of physical and environmental interactions of MHK devices using open-source modeling frameworks. The dataset includes presentations, tutorials, theoretical documentation, and software setup instructions related to modeling wave and current energy devices. It covers both conceptual and real-world applications, such as channel flow and riverine or coastal sites like the Tanana River and Yakutat, Alaska. Instructions for installing and customizing the Delft3D and SWAN modeling suites with the SNL-developed modules are included, along with test cases and example scenarios. All data units and modeling parameters are labeled, and the dataset assumes access to proprietary software components (e.g., Deltares license files for Delft3D FM Suite) and some familiarity with hydrodynamic modeling tools.
