WebIn hydrology, a rating curve is a graph of discharge versus stage for a given point on a stream, usually at gauging stations, where the stream discharge is measured across the stream channel with a flow meter. [1] Numerous measurements of stream discharge are made over a range of stream stages. Web10.7 Example use of an FDC. Let’s explore one potential use of flow duration curves: examining the differences between two sets of flow data. From the line plot of the discharge, it looked like the flow regime may have shifted a bit in the data between the early years and newer data. Let’s use flow duration curves to examine potential ...
