    Sediment delivery ratio (SDR) is defined as the sediment yield from an area divided by the gross erosion of that same area. SDR is expressed as a percent and represents the efficiency of the watershed in moving soilFile Size: 314KB

Sediment-Storage Design Criteria - USDA

    https://directives.sc.egov.usda.gov/17514.wba
    The sediment delivery ratio (ratio of sediment yield to gross erosion) is estimated from the relationships discussed in Chapter 6. The product of gross ero- sion and the sediment delivery ratio is the sedi- ment yield used in computing the design requirements.

    Novotny and Olem (1994) related the runoff coefficient C with sediment delivery ratio DR in the power form as (18) DR = α C β where α and β are, respectively, the coefficient and exponent of the power relationship, and DR, is a dimensionless ratio of the sediment yield Y to the potential maximum erosion A: (19) DR = Y A The runoff coefficient, C, is a dimensionless ratio of actual runoff, Q, to total rainfall, P: …Author: P.K.

    Sediment delivery ratio (SDR) is traditionally defined as the fraction of upland gross erosion that is transported out of a defined area, e.g., a plot or catchment. It is, effectively, an index of sediment transport efficiency.

    Notes: Enter Table 11-2b with 225 tons of soil loss and a delivery ratio of 40%. Interpolate between 1.84 and 2.76 (for 200 and 300 tons soil loss respectively) for a soil loss below the crest of 2.07 acre-feet.

    This ratio tends to decrease with increasing basin size due to storage effects along floodplains or in structural valleys, and ranges from virtually complete delivery for short, steep catchments to less than half of the sediment load for large, continent-spanning rivers.
