Patterns and rates of sedimentation within POTirua Harbour.Coastal Management Ltd Consultancy Report(CR2009/I) for POTirua City CouncilStudy of the pattern and rate of sedimentation on the POTirua Harbour seafloor over thelast 160 years, based on a comparison of hydrographic surveys made between 1849 and2009 (detailed analysis of sedimentation rates mainly uses the surveys of 1974 and 2009).Both arms of the Harbour have been a relatively stable geomorphic environment over thelast 7,300 years or more. They have progressiveIy shallowed from deposition of mud andsand at a net average rate of 1.0-1.5 mintyr. Innlling has progressed in the context of arecently rising global sea-level of 1.95 mintyr. Since forest clearance and landdevelopment began, rates of sedimentation have progressiveIy increased. Between 1974and 2009, they increased <strong>to</strong> 5.7 min/yr in the Onepo<strong>to</strong> Arm and 9.1 mintyr in thePauatahanui Inlet. The tidal prism has been reduced by 1.7% and 8.7% respectivelyduring that time. At current deposition rates Pauatahanui Inlet will have ceased <strong>to</strong> existas an estuary within 145-195 years and Onepo<strong>to</strong> Arm within 290-390 yearsGrange, K. R. and P.

Determined that the bed morphology is largely stable with most cross sectionalprofiles OScillating around zero change, with a maximum erosion of 28mm and maximumaccretion of 47mm. Most changes are only in the range of plus or minus 2mm, and thereis a mean rate of accretion of 2.9mm. Deltas, and beaches at high tide level display a lessstable profile. S<strong>to</strong>rm events appear not <strong>to</strong> change erosion and deposition in the Inlet(with the exception of scour and deposition at bayhead deltas) indicating that sedimentdelivered was deposited elsewhere or lost <strong>to</strong> the system.
