Part 1: Flow Duration Curve Analysis The flow duration curve for the Barron River at Mareeba can be plotted from the data given in Table 1, for two time periods; 1916-1950 and 1950-2009. 1. Plot the flow duration curves for the Barron River for the two time periods using the data given in Table 1. (1 mark) 2. Using your plots of the flow duration curves, how much percentage of time does the streamflow at 200 m3/s occur for both time periods? (1 mark) 3. Describe the change in the shape of the flow duration curves for the two time periods. (4 marks) 4. Provide possible explanations for the change in flow duration curves observed between the two time periods. (4 marks)
