Cienna is using SWASH, a numerical modeling tool for simulating wave dynamics, to investigate wave energy converter (WEC) interactions in coastal environments. As an initial step, the model is being applied to Oregon State University’s Directional Basin, where a WEC is integrated into the physical setup. Model performance is evaluated by comparing simulation results to measured wave gauge data, allowing for calibration and validation. This approach builds toward adapting the model for nearshore conditions in Hawaiʻi, with the long-term goal of supporting sustainable development of wave power and enhancing coastal resilience.
