Variability in Suspended-Sediment Concentration over Mobile Sand Beds
Publication: Journal of Hydraulic Engineering
Volume 131, Issue 8
Abstract
Lateral and longitudinal variability in suspended-sediment concentration was investigated over dune and upper-regime plane beds under steady, uniform flow in a laboratory flume. A much greater sampling time was required to reliably predict mean concentration in a dune bed than for an upper-regime plane bed. Laterally separated, simultaneous samples over both dune and upper-regime plane beds were poorly correlated.
