Modeled nearshore wave propagation was investigated downstream of simulated wave energy con-verters (WECs) to evaluate overall near- and far-field effects of WEC arrays. Model sensitivity to WECcharacteristics and WEC array deployment scenarios was evaluated using a modified version of an in-dustry standard wave model, Simulating WAves Nearshore (SWAN), which allows the incorporation ofdevice-specific WEC characteristics to specify obstacle transmission. The sensitivity study illustrated thatWEC device type and subsequently its size directly resulted in wave height variations in the lee of theWEC array. Wave heights decreased up to 30% between modeled scenarios with and without WECs forlarge arrays (100 devices) of relatively sizable devices (26 m in diameter) with peak power generationnear to the modeled incident wave height. Other WEC types resulted in less than 15% differences inmodeled wave height with and without WECs, with lesser influence for WECs less than 10 m in diameter.Wave directions and periods were largely insensitive to changes in parameters. However, additionalmodel parameterization and analysis are required to fully explore the model sensitivity of peak waveperiod and mean wave direction to the varying of the parameters.
