*: Annual Recurrence Interval (ARI) is defined as the average annual rate of occurrence of an event. In this instance, a ARI 1:5 flow is the mean monthly flow that that is NOT equalled or exceeded one year in five in the record under consideration; a lognormal distribution is used to calculate the ARIs. **: A Flow Duration Curve (FDC) is a plot of flows ranked from highest to lowest. In this instance the 80% exceedance value is the mean monthly flow in a particular month that is exceeded for 80% of the record under consideration. |
