A micro‐morphological study of intertidal estuarine surfaces in Pauatahanui Inlet, Porirua Harbour

Monthly changes in the elevation of the intertidal flats in Pauatahanui Inlet over a 15‐month period were measured to the nearest 0.5 mm. Changes were small, mostly less than ±10 mm, and erosional events were as frequent as depositional ones. Net deposition of 2.9 mm was recorded over a 12‐month period. The mid‐tidal area, high tidal sand beaches, and the deltas of the inflowing streams are the least stable zones.
