Splet01. apr. 2024 · The scaling parameters for swash overtopping typically include the wave height ( H ), wave length ( L) or wave period ( T ), beach slope (β), and the vertical elevation of the structure crest or beach crest ( zc) above a datum, usually the still water level (SWL). This is also termed the truncation elevation or freeboard.
