Abstract
The morphodynamic and morphosedimentary development of drift-aligned and swash-aligned coarse clastic barriers plays an important role in the evolution of paraglacial coasts. This paper discusses the development of two contrasting barriers attached to a drumlin headland at Story Head on the Atlantic coast of Nova Scotia, southeastern Canada. A 3-4 mm a super(-1) sea-level rise is forcing rapid barrier changes, including landward migration (rollover) of the swash-aligned barrier at 5-8 m a super(-1), and barrier thinning, elongation and breaching. Morphological development reflects the highly variable longshore distribution of wave power, imposed initially by the topography of the drumlin and its position in the incident wave field, and later by morphosedimentary feedback resulting from such gradients.
