A third–generation wave model that computes random, short–crested, wind–generated waves in coastal regions and inland waters. The physics accounted for in the SWAN model includes:

wave propagation in time and space, shoaling, refraction due to current and depth, frequency shifting due to currents, and nonstationary depth;

wave generation by wind;

three– and four–wave interactions;

whitecapping, bottom friction, and depth–induced breaking;

wave–induced setup;

propagation from laboratory up to global scales; and

transmission through and reflection from obstacles. A copy of the FORTRAN code is available upon registration.
