Total LoadThe sediment transport rate may be measured by weight (units: N/s), by mass (units: kg/ s) or by volume (units: m3 /s). In practice the sediment transport rate is often expressed per unit width and is measured - Yehia.pptx

the basic modes of particle motion are rolling motion, sliding motion and saltation motion.
Many researchers attempted to predict the rate of bed load transport. The first successful development was proposed by P.F.D. du Boys in 1879. Although his model of sediment transport was incomplete, the proposed relationship for bedload transport rate (Table 10.1) proved to be in good agreement with a large amount of experimental measurements

1. Total Load Transport

2. Introduction The transport of bed material particles may be in the form of either bed-load or bed-load plus suspended load , depending on the size of the bed material particles and the flow conditions. The suspended load may also include some wash load (usually, clay-silt dominated fraction smaller than 8 mm).

3. Bed material: The material, the particle sizes of which are found in appreciable quantities in that part of the bed that is affected by transport . Bed load: The sediment in almost continuous contact with the bed, carried forward by rolling, sliding or hopping. Suspended load: That part of the total sediment transport which is maintained in suspension by turbulence in the flowing water for considerable periods of time without contact with the stream bed. It moves with practically the same velocity as that of the flowing water
