Summary

St Andrews Bay is a semi-circular embayment bound by headlands. The present-day sedimentary environments have grown in response to tide- and wave-induced currents and material transfer during and since the Holocene (Flandrian) transgression. The long-shore current pattern is controlled by the shape and orientation of the embayment in relation to wave approach.

Net longshore sand transport in the embayment consists of two ‘cell’ systems moving in opposite directions and converging towards the head of the embayment. This wave-induced sand transport pattern is implemented by the tidal circulation pattern. The bay-head sand deposits, formed by the convergence of the two cell systems, are further shaped to ebb-delta and back-beach sand environments by estuarine and aeolian processes respectively.
