"The Johnstone River of North Queensland flows in two main branches through highly erodible caneland before discharging to the Coral Sea. The hydrodynamics and sedimentary processes of the Johnstone River estuary were analyzed to estimate the relationship between river dynamics and volume of sediment deposited in the estuary and discharged into the sea. Numerical models were used to analyze hydraulics of selected cross-sections of the river and to estimate the volume of sediment transport. Based on the results obtained from a hydro-sedimentological 1D model the average annual sediment discharged into the sea was estimated to be of the order of 11,000 to 22,000m3. Nomograms prepared from the results allow the estimation of the volume of sediment transport discharged into the sea for specified flow discharges in both branches of the river."--t.p.
