Sedimentology, 1972
ABSTRACTApplication of sieve and size‐shape analyses (Moss, 1962) to natural and artificial bed‐load deposits of shallow, unidirectional currents revealed that a textural sequence parallels one of primary structures. With increasing grain size and/or transporting power, sedimentary characteristics followed the stepwise pattern: fine ripple bed stage ...

New Total Sediment‐Load Sampler
Journal of Hydraulic Engineering, 1992A new total sediment-load sampler is designed and tested in a flume. The new instrument consists of a bed-load sampler and a suspended-load sampler, both attached to a supporting frame. The suspended-load sampler consists of seven intake nozzles, which are connected to plastic hoses and operated by pumps.

Washload and Fine Sediment Load
Journal of Hydraulic Engineering, 1986Washload and fine sediment load should not be used synonymously. In streams with large concentrations of fines, the sediment size D\d1\d0 may be much smaller than 0.0625 mm. The fluid becomes very viscous at low concentrations of clays and the reduced settling velocity inhibits the exchange of sediment particles between the bed and the suspension.

Summary Most sediment loads are estimated from sediment-rating curves created by performing a linear least-square regression on log-transformed sediment load–discharge data. When log-transformed sediment load–discharge data plots result in concave or convex curves, such regressions under- or overestimate sediment loads.

Bed‐Load and Suspended‐Load Transport of Nonuniform Sediments
Journal of Hydraulic Engineering, 1991Methods are available for the computation of the bed-load and suspended-load transport rates of uniform sediments. However, limited studies exist for nonuniform sediments. These studies, in general, lack simplicity, and often make use of various correction factors to be read from a series of tables and graphs.
