Suspended Load Transport of Sediment Mixtures
Journal of Hydraulic Engineering, 1986Careful experiments were conducted on alluvial beds of four sediment mixtures having different arithmetic mean diameters and standard deviations. The suspended load transport rates of individual fractions were measured and compared with both Einstein's and Holtroff's methods of calculation of suspended load for individual fractions.

Frequency distribution for suspended sediment loads
Water Resources Research, 1989A method is described for deriving a frequency distribution for suspended sediment loads. The method uses a curvilinear regression relation between the logarithm of annual flood peaks and the logarithm of suspended sediment loads associated with that flood peak.

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.

Artificial intelligence for suspended sediment load prediction: a review
Environmental Earth Sciences, 2021The estimation of sediment yield concentration is crucial for the development of stream ventures, watershed management, toxins estimation, soil disintegration, floods, and so on. In this study, we summarize various existing artificial intelligence (AI)-based suspended sediment load (SSL) estimation models to calculate the suspended sediment load, to ...

Suspended Wash Load Transport of Nonuniform Sediments
Journal of Hydraulic Engineering, 2010The results of an experimental study on transport of suspended wash load through a coarse-bed stream are presented. The experiments were conducted under different concentrations of fine suspended sediment (wash load of uniform size, 0.064 mm diameter) and with three different coarse-bed sediments: two having uniform sizes and one with nonuniform size ...

Cokriging estimation of daily suspended sediment loads
Journal of Hydrology, 2006Daily suspended sediment loads (S) were estimated using cokriging (CK) of S with daily river discharge based on weekly, biweekly, or monthly sampled sediment data. They were also estimated with ordinary kriging (OK) and a rating curve method. The estimated daily loads were compared with the daily measured values over a nine-year-period.

Suspended sediment load of Bulgarian rivers
GeoJournal, 1996In 1951–52, a nationwide sediment gauge network was initiated in Bulgaria. In 1992–93 a Computerized Information Base of Sediment Data for the Bulgarian rivers was developed. Some analysis has shown that the long term sequences of the annual suspended sediment load of the rivers are not homogeneous. The period 1980–90 has received special attention due

Estimation of suspended-sediment rating curves and mean suspended-sediment loads
Journal of Hydrology, 1991Suspended-sediment loads are often estimated from an empirical relation between suspended-sediment load (L) and streamflow (S). This relation is usually defined as a power function, L = aSb, and is referred to as a suspended-sediment rating curve. This function can be formulated as either a linear or non-linear model to find the solution of the rating ...

Single-station estimates of suspended sediment loads using sediment rating curves
Canadian Journal of Civil Engineering, 1993Sediment rating curves in conjunction with daily flow data have often been used to estimate the total mass of sediment flowing past a given river cross section over relatively long periods of time. Techniques are presented that seek to make the best use of limited noncontinuous suspended sediment concentration data to generate nine partial years of ...

Suspended sediment load in the Amazon basin: An overview
GeoJournal, 1989In this report the state of knowledge of sediment transport by rivers of the Amazon drainage basin is reviewed. On an annual basis the Amazon river transports about 1200×106 tons of sediment from the South American continent to the ocean, which puts it among the world's largest rivers in this respect. The main source of sediment is erosion in the Andes
