Rating Curve The rating … WebRating curves are developed on infrequent, as-needed basis, by taking direct measurements of depth and flow, and plotting the curve from this data. The curve is then used to convert real-time measurements of depth into real-time values of discharge. WebA flow duration curve characterizes the ability of the basin to provide flows of various magnitudes. Information concerning the relative amount of time that flows past a site are likely to equal or exceed a specified value of interest is extremely useful for the design of structures on a stream. hanna valtonen oona kannonlahti
