-The wave direction in the parameter configuration ​file follows ​the oceanographic convention in which zero indicates that the waves are propagating towards the north and 90 towards the east. Shoreline orientation is also measured clockwise relative to the azimuth following the convention shown in the figure below, being a shoreline orientation 0 deg when oriented S-N and 90 deg when oriented W-E. By using a local coordinate system at every node along the coast, CoastalME allows the plan-view shoreline to take on arbitrary local orientations,​ and even fold back upon itself, as complex shapes such as capes and spits form under some wave climates.+The wave direction in the parameter configuration ​uses the [[https://​en.wikipedia.org/​wiki/​Azimuth#​True_north-based_azimuths|'​true north-based azimuthal system'​ ]] which is the oceanographic convention in which zero indicates that the waves are propagating towards the north and 90 towards the east.
