Sandwave movement under tidal and wind-driven currents in a shallow marine environment: Adolphus Channel, northeastern Australia

Modeling wave and wind climate effects on tidal sand wave dynamics: A North Sea case study

“…Here we observe that especially the migration rate shows large seasonal variations, which support variation of observed migration due to storm effects (Fenster et al, 1990) as well as seasonal variations (Harris, 1989). The mean migration rate in summer is 3.4 m/yr (with standard deviation = σ 1.7 m/yr) and 8.1 m/yr in winter ( = σ 2.2 m/ yr).…”

“…In other locations variations in sand wave migration have been observed, and these are associated with variations in wind conditions (Le Bot et al, 2000;Krewinkel et al, 2017). In the Adolphus Channel, northeast of Australia, Harris (1989) shows seasonal reversal of sand wave migration during the monsoon season.…”

Sediment mobility due to currents and waves in the Torres Strait–Gulf of Papua region

“…One zone observed to have changed direction seasonally is the Adolphus Channel at the northern tip of Cape York. This seasonal reversal has been previously observed from reversing bedform direction (Harris, 1989). The other main area is in the shallow waters to the west of Cape York.…”

“…The model allows the sediment to leave the model grid by settling and/or lateral transport; however, no resuspension mechanism is included in the model. The NGBR sediment plume indicates a reverse in direction seasonally as found by Wolanski et al (1988) and suggested from bedforms (Harris, 1989). Monsoon conditions lead to a large component of sediment moving north-eastwards, along the south coast of PNG.…”

Nearshore bedform instability in the eastern entrance to the Qiongzhou Strait, South China Sea

“…3). The average bedform celerities in the present study are larger than that in a term of daily dimension, with similar spatial scale, water depth and grain size measured in the fields, such as, 0.95 cm/ day in the eastern part to Long Island, America (Fenster et al, 1990), 0.25-0.75 m/day in the Adolphus Strait, Australia (Harris, 1989) and the southern Bight of the Taiwan Strait (Wang et al, 1993). But the celerity in the present study is smaller than that in a term of second dimension such as 0.01-0.09 m/s measured in the Yangtze Estuary (Cheng et al, 2001).…”
