Quantification of coastal bank erosion rates in Western Port

[摘要] This report presents the findings from a 12-month monitoring project that investigated the rates, processes and spatial distribution of coastal bank erosion in Western Port Bay, Victoria. The project was commissioned by Melbourne Water in 2012 to address a high priority research need, namely, to estimate the contribution of coastal erosion to nutrient and sediment budgets in the bay. The focus of the study is an 8.6 km stretch of coastline west of Lang Lang that had been identified as an erosion hot-spot in the bay. Previous work at the site included a sediment tracer study by the CSIRO (Wallbrink et al. 2003), which had estimated that the banks were supplying up to 32 % of the fine sediment in the bay, compared to 68 % from catchment sources.
