Fluvial erosion, transport and deposition (continued)

• Where z is bed elevation, t is time

• qsb is bedload sediment transport rate per unit channel width

• Ke and p are parameters

• ? is shear stress on bed

• d is sediment grain size with porosity ? and fall velocity ?

• ?s is sediment density and ? is fluid density

• ? is dimensionless sediment transport rate

• 1/?? is dimensionless shear stress, and 1/?c is dimensionless critical shear stress.
