Swash Zone Wave Characteristics From Supertank

Measured values of shoreline wave setup and shoreline wave heights are summarized from the SUPERTANK Laboratory Data Collection Project. Water surface elevation time-series in the swash zone were measured by capacitance wave gages that were partially buried in the sand beach. As a result, wave measurements were obtained on the actively eroding/accreting beach-face where little data has traditionally been available. Results presented in this paper include examples of wave transformation across the entire beach profile. Mean water level and wave height conditions at the still water shoreline are then summarized for 19 sets of random wave conditions tested during the first two weeks of the SUPERTANK Project.
