Summary
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 ± 10mm, 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.
