Meyer-Peter and Muller(1948) An empirical relation based on a large number of experiments with uniform sediment 3–29 mm, in flumes 20–200 cm bedload transport equation applicable to gravel-bed rivers of coastal British Columbia is the Meyer-Peter & Muller (M-P&M) equation Ф = 8(θ−θcr) 3/2 (5) E. Nielsen(2000)- Ф = 12 θ1/2 (θ−θcr) (6) F. The Bijker Equation: Bijker derived the total transport in to two parts, the bed load and suspended load transport. The bed load transport is calculated using the Kalinke-Frinjlink formula in which combined action of wave and current is accounted by a modification of the bed shear stress. 424
