In Western Australia, a number of coastal rivers and estuaries have suffered from eutrophication since the 1960’s. Often the focus of the threat to water quality in these areas has been agriculture because of its extensive nature and widespread use of highly soluble fertilisers. Over recent years a focus on nutrient inputs, outputs and nutrient balance in a number of projects provides an opportunity to compare the relative nutrient threats from the agricultural and urban sectors, placed in the context of increasing urbanisation and development. These disparate data sets also allow a comparison of nutrient inputs in each sector in …

The ecology of estuaries on the south coast of Western Australia has been disrupted by increased nutrient and sediment discharge from predominantly rural catchments. Seagrass beds have been replaced by macroalgae, and toxic algal blooms threaten human and animal health, and reduce amenity. A range of conventional management actions are available to reduce nutrient loss at source, and it is important to evaluate possible reductions, and costs, so that limited funds can be targeted to realise the greatest moderation of nutrient loss. A lumped landuse nutrient generation rate model was developed for four catchments (Wilson Inlet, Oyster Harbour, Torbay Inlet …
