A preliminary study of sediment transport parameters, Rio Puerco near Bernardo, New Mexico

Abstract

Preliminary findings of a study of sediment transport in streams with high concentrations of suspended fine sediment indicate that for the Rio Puerco near Bernardo, N. Mex., the velocity varies logarithmically with depth, and the concentration distribution for several size classes of sand may be described by a conventional distribution equation if the fall velocity of the sand is corrected for the influence of the fine sediment. A corrected fall velocity, empirically defined for a temperature of 24 C and for concentrations of as much as about 150,000 parts per million, is given.
