Answer 19 Rating curve Because 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 The rating curve is usually plotted as discharge on xaxis versus stage surface elevation on yaxis Answer 20 flood frequency curve Because A flood frequency curve is a tool to extrapolate how often a flood of a given discharge will occur A flood frequency curve can be constructed by plotting a graph of discharge versus recurrence interval This can easily be See Answer
