An industry standard wave modeling tool was utilized to investigate model sensitivity to input parameters and wave energy converter ( WEC ) array deployment scenarios. Wave propagation was investigated downstream of the WECs to evaluate overall near- and far-field effects of WEC arrays. The sensitivity study illustrated that both wave height and near-bottom orbital velocity were subject to the largest potential variations, each decreased in sensitivity as transmission coefficient increased, as number and spacing of WEC devices decreased, and as the deployment location moved offshore. Wave direction was affected consistently for all parameters and wave period was not affected (or negligibly affected) by varying model parameters or WEC configuration.
