Abstract


  • Sediment budgets are fundamental approaches in coastal studies for allowing estimates

    of volumes of sediments entering and exiting a selected area of the coast, resulting in

    net erosion or accretion of that compartment under consideration. This assessment is

    crucial for understanding current processes and predicting future effects of sedimentimpact

    activities, promoting the sustainability of coastal environments over the next

    centuries. In this paper we present a series of preliminary spatial, sedimentological and

    geophysical analyses undertaken in order to understand the sources, sinks, transport

    and pathways for the sediment budget of the Shoalhaven coast, a compartment whose

    sediment provision is supplied primarily by the Shoalhaven River (draining a catchment

    of 7,151 km2) and that stretches ~32 km from the rocky headland of Black Head at

    Gerroa (north) to the Beecroft Peninsula near Currarong (south). Analysis included the

    use of sub-bottom profiler, ground penetrating radar, RTK-GPS, aerial photographs,

    satellite images, LiDAR, echosounding, computer modelling, as well as grain size

    parameters from ~200 sediment (and mineralogy for selected) samples from the estuary,

    beach and shoreface.
