Description
A regional flow duration curve (FDC) is an averaging of multiple FDCs from a number of gauges in a particular geographic region which exhibits similar traits (climate, geology, etc.). There are a number of ways to regionalize a flow duration curve given gauge data (statistical regression, parametric fitting, or graphical methods (Castellarin et al., 2004)). The method used here is a graphical method similar to that used by Smakhtin et al. (2000) in which each individual gauge's flow duration curve is normalized based on a metric like drainage area, long-term averge flow, or another flow metric like Q2 or bankfull discharge. These normalized flow duration curves are then averaged together (using their period length as a weighting factor as described by Niadas (2005)) to determine a regionalized FDC. Then for an ungauged basin in the same geographic region, if the normalizing metric is estimated it can be combined with the regional FDC for an estimate of the FDC at the unguaged site.
