The Computation of fluvial sediment discharge computes fluvial sediment discharge by allowing the user to choose between five described bedload formulas and eight described bed-material formulas. The bedload discharge formulas are those of Schoklitsch (1934), Kalinske, Meyer-Peter and Muller (1948), Rottner, and Einstein. The bed-material formulas are those of Laursen, Engelund and Hansen, Colby, Ackers and White, Yang sand formula, Yang gravel formula, Einstein, and Toffaleti.|
Numerous sediment-discharge formulas have been proposed in literature. Selection of the thirteen formulas used in SEDDISCH was based on: (1) theoretical background, (2) extent of testing by original author and independent investigator(s), and (3) extent of use by engineers and researchers. The user is asked to choose from these formulas based on which field data are available.
