Coarse‐sand beach ridges at Cowley Beach, north‐eastern . . . Hummocky structures in the upper facies indicate that the nucleus of the beach ridge forms as a berm at +2·5 m Australian Height Datum, equivalent to the fair-weather swash limit during high tide The lower facies comprises a sequence of seaward-dipping reflections
A theory (involving tropical cyclones) on the formation of . . . A theory is presented that coarse-grained sand beach ridge plains in northeastern Australia have developed their final form (i e the height of the ridges above sea level) as a result of marine inundations generated by intense tropical cyclones
Beach Ridge - an overview | ScienceDirect Topics However, this is unlikely the case for sand ridges within the coarse-grained beach ridge plains of the wet tropics of Northeast (NE) Australia (Figure 5 1) Rather, it is more likely that units of sand between 0 1 and 1 5 m thick are deposited onto the crests of a ridge during marine inundations; a ridge will grow in height progressively with
Anatomy of sand beach ridges: Evidence from severe Tropical . . . For example, eyewitness accounts show that an entire coral shingle beach ridge up to several meters in height and hun-dreds of meters in length can be emplaced during a single storm event [Blumenstock, 1958; Maragos et al , 1973; Nott, 2003]

Sand beach ridges record 6000 year history of extreme . . . The textural characteristics, height above sea level and results of numerical storm surge and wave modelling suggest the elevation of the sand beach ridges at Cowley Beach is due to high magnitude low frequency storm surges and waves generated by extreme intensity tropical cyclones
