Abstract
The Atlantic Geoscience Centre sediment transport model (SEDTRANS92) is an ANSI standard FORTRAN-77 numerical model that has been under development for the last 9 years. For given input data of wave, current, and seabed conditions, SEDTRANS92 applies combined wave-current bottom boundary layer theories to derive enhanced bottom shear stresses. Then it calculates sediment transport rates for a given grain size using one of seven algorithms: Engelund and Hansen, total load equation; Einstein-Brown, bedload equation; Bagnold, total load equation; Yalin, bedload equation; Ackers and White, total load equation; Smith, suspended load method; and the cohesive sediment transport algorithm of Amos and Greenberg. This model adopts new advances of bottom boundary layer theory and recently available field measurements of sediment transport rates on the Scotian Shelf. The model gives reasonable predictions compared to the field measurements.
