Daily. Hourly. Weekly. Depends on storm/wave activity. Any change in morphology of the beach changes the relationship between a vertical datum (MHW) and a horizontal position on the beach. Because it isn't practical to hire a surveyor daily to pin MHW, the courts adopted the last high tide swash (LHTS) as the proxy.
