Overwash occurrence consequent on morphodynamic changes following lagoon outlet closure on a coarse clastic barrier
A temporal sequence of dissipative barrier, reflective barrier and inner reflective (barrier face)/outer dissipative (subtidal) wave regimes match respectively periods of barrier crest build up by crestal dune development, barrier crest instability
(barrier width increasing , height decreasing) due to rhythmic overwash and a return to barrier crest stability with limited aeolian accretion. Two barriers at different stages are discussed.
An exploratory approach to coarse clastic barrier development is based on a conceptual outline of shoreline processes around drumlin islands and likely interaction among them. The case study is the eroding drumlin archipelago at Clew Bay, western
Ireland. Sediment released by an erosional front is forming beach ridges, spits, and transient linkages. Transfer of sediment is significant for barrier form and control of coastal change. Linking of adjacent drumlins affects dispersal of material within

Interglacial stage during which Inner Barriers were formed| (iii) Last Glacial reworking of barrier and dune sands by westerly winds| (iv) Postglacial Marine Transgression during which the Outer Barriers were initiated| (v) Mid-Holocene stage following
cessation of sea-level rise ca. 6000-6500 yr B.P. on this coast, and involving progradation of Outer Barriers in some embayments| and (vi) Late Holocene episodic eolian reworking of dune complexes and Outer Barriers. The relatively high wave and wind energy
as well as the tectonic setting of the central N.S.W. coast results in somewhat different geomorphic histories from barrier-island coasts in North America and Europe.
