River rating curve
Web(1986) suggests that most estimates of river load by rating curve method will have been too low. Other scientists have proposed a statistical bias-correction factor to remove the degree of underestimation by rating curve method (Duan, 1983; Ferguson, 1986). The latter method is meant to correct actual loads, which are underestimated, because the WebOct 10, 2014 · A rating curve is a plot of the stage of the water versus the flow that the stream had at that stage. An example of a rating curve is shown in the following figure. The stage is the height of the water surface above some datum point, which is usually taken as the deepest point in the stream channel.
