Determination of the Discharge of Bottom Sediments in River Beds Composed of Soil of Varying Grain Size

Resumo

It is proposed that discharges of particles of fractions which are in motion under given hydraulic conditions be summed in order to determine the discharge of bottom sediments in channels composed of soils of varying grain size. The shading effect of large particles on small particles is taken into account and the use of a probabilistic relationship based on the improved and simplified Rossinskiy model is proposed for calculating the discharge of particles in different fractions.
