Prediction of sediment, particulate nutrient and dissolved nutrient concentrations in a dry tropical river to provide input to a mechanistic coastal water quality model

Despite the absence of any obvious direct relationship between flow and dissolved nutrient concentrations (in this case dissolved organic nitrogen, DON) concentrations in the Fitzroy River (left), a Generalised Additive Model is able to predict dissolved nutrient concentrations as a function of flow in the Fitzroy River and one of its tributaries (right).142
