    Abstract This document reports on a project reconstructing the
    sedimentation history of the Pauatahanui Inlet, relating this
    to changes in catchment land cover during the last 150 years.
    The report quantifies the changes in average sediment
    accumulation rates (SAR) due to large scale deforestation,
    quantifies spatial variation in SAR, particle size and heavy
    metal profiles between urban and rural subcatchment outlets
    and the central mud basin of the inlet, and relates observed
    sediment particle size and heavy metal concentation profiles
    in the inlet cores to catchment land cover history. It also
    provides an assessment of potential future SAR's in the
    Pauatahanui Inlet based on 2003 land cover and management
    practices.
