Water turbidity is influenced by the urban and industrial wastes that drain from the watershed and the flushing of the estuary by clear oceanic water. In order to contrast the imaging of objects underwater by light or sound, it is necessary to understand the role played by the scatterers in the water that cause turbidity. Using five reference sites, the grain size, the number of grains per litre and the turbidity have been compared before and after rain. Three Sydney area estuaries have been observed to have similar turbidity increases with increasing distance from the sea. {"type": "Polygon", "coordinates": [[[151.07, -33.87], [151.29, -33.87], [151.29, -33.83], [151.07, -33.83], [151.07, -33.87]]]} 151.07 151.29 -33.87 -33.83 Oceans | Coastal Processes | Estuaries Oceans | Marine Sediments | Sediment Grain Size Oceans | Marine Sediments | Turbidity grainsize_size_category rainfall_amount secchi_depth_of_sea_water turbidity Link to Project report documentDigital HTML Unnamed resource documentDigital HTML
