Title: The Enhanced Flow Duration Curve by Rick Koehler
 
Abstract:
Flow duration curves (FDCs) are a common hydrologic analysis technique examining the cumulative distribution of a streamflow record. Yet despite multiple variations developed over the past 100 years, FDCs have never been able to display or quantify day-to-day streamflow information…until now.
Presented is a way to create “enhanced” flow duration curves (eFDCs) simply by adding the lag (1) autocorrelation scatterplot to the basic FDC. This produces a graphic showing the daily streamflow properties of magnitude, frequency, duration, timing, day-to-day discharge change, and temporal autocorrelation across different flow ranges. Also displayed are graphical regions of flow increases (dQ/dt > 0), decreases (dQ/dt < 0) , or persistent flow (dQ/dt = 0).
 
The result is a set of eFDCs which can provide detailed historic streamflow summaries, provide guidance for restoration efforts, monitor hydrologic alterations, quantify streamflow change on a day-to-day basis, or provide a detailed model analysis technique.
