Ref Dimensionless Sediment, Bedload Rating Curves

These curves should be developed for stable reference reach sites representing stable streams. A similar relation can be stratified for "poor" stability or unstable streams. These reference curves are needed in order to establish sediment rating curves for the calculation of flow-related sediment increases and to establish an annual sediment yield estimate for proportioning various contributing sediment sources. Examples of dimensionless suspended and bedload rating curves are shown in Figures 56 and 57 and discussed in the Dimensionless SRCs reference section.
