The water quality of the upper reaches of Darwin Harbour are particularly prone to tidal influences during the dry season when there is negligible river inflow to the estuary. The extent of this influence and the amount of material that is transported by the tide into and out of these upper reaches is not known. In September 2002, the flux of sediment, nutrients and other water quality parameters was monitored, at two sites in the Blackmore River estuary, over spring and neap tides.
Overall, the amount of material being exported from the upper reach of the Blackmore River estuary, over spring and neap tides, was similar. The study provides the first empirical evidence that the large tides of Darwin Harbour serve to transport material into and out of the Harbour, rather than “remove or flush” the Harbour of material as some members of the public may perceive.,
