Estimating fluvial sediment transport: The rating parameters
Correlations between suspended sediment load rating parameters, river basin morphology, and climate provide information about the physical controls on the sediment load in rivers and are used to create predictive equations for the sediment rating parameters. Long-term time-averaged values of discharge, suspended load, flow duration, flow peakedness, and temporally averaged values of precipitati...
متن کاملSediment Transport in Unsteady Flow Conditions
Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
متن کاملGrain size distribution effects on phosphate sorption by fluvial sediment: implications for modelling sediment- phosphate transport
A sensitivity analysis was performed on a sediment-phosphate transport model by determining the phosphate sorption characteristics of separated size fractions and prepared size distributions of fine-grained ( < 64 jum) river sediment typically transported in two southern Ontario streams. The Langmuir equation was used to quantify phosphate release from the sediment. Results of the study indicat...
متن کاملTransport of Gravel and Sediment Mixtures 3.1 Fluvial Phenomena Associated with Sediment Mixtures
When ASCE Manual No. 54, “Sedimentation Engineering,” was first published in 1975, the subject of the transport and sorting of heterogeneous sediments with wide grain size distributions was still in its infancy. This was particularly true in the case of bedload transport. The method of Einstein (1950) was one of the few available at the time capable of computing the entire grain size distributi...
متن کاملThe Effect of Convergence and Divergence on Flow Pattern and Sediment Transport in Lateral Intakes
Water supply at a desired rate at any time to meet the water requirements regardless of river discharge must be considered in the general design of intakes provided that the needs do not exceed the river flow. Due to the lack of necessary information in this field and the importance of sediment transport to the lateral intakes at river bends, this study aimed at understanding the mechanism of t...
