Densimetric Monitoring of Suspended-sediment Concentrations, Northeastern Georgia
Differential pressure transducers can be used to monitor the suspended-sediment concentration in a water column. Suspended sediments with densities greater than water increase the fluid density, which is determined by measuring the fluid pressure change between two depths. Lewis and Rasmussen (1999) used a densimetric technique under controlled conditions to determine suspended-sediment concent...
متن کاملSuspended sediment and sediment-associated contaminants in San Francisco Bay.
Water-quality managers desire information on the temporal and spatial variability of contaminant concentrations and the magnitudes of watershed and bed-sediment loads in San Francisco Bay. To help provide this information, the Regional Monitoring Program for Trace Substances in the San Francisco Estuary (RMP) takes advantage of the association of many contaminants with sediment particles by con...
متن کاملSystematic Sampling for Suspended Sediment
Because of high costs or complex logistics, scientific populations cannot be measured entirely and must be sampled. Accepted scientific practice holds that sample selection be based on statistical principles to assure objectivity when estimating totals and variances. Probability sampling--obtaining samples with known probabilities--is the only method that assures these results. However, probabi...
متن کاملMonitoring baseline suspended sediment in forested basins: the effects of sampling on suspended sediment rating curves
Rating curves are widely used for directly assessing changes in the suspended sediment delivery process and indirectly for estimating total yields. Four sampling methods were simulated over a 31-day record of suspended sediment from the North Fork of the Mad River near Korbel, California. The position and size of the four groups of plotted slope/intercept pairs indicated differences in bias and...
متن کاملParameterization of Time-Averaged Suspended Sediment Concentration in the Nearshore
To quantify the effect of wave breaking turbulence on sediment transport in the nearshore, the vertical distribution of time-averaged suspended sediment concentration (SSC) in the surf zone was parameterized in terms of the turbulent kinetic energy (TKE) at different cross-shore locations, including the bar crest, bar trough, and inner surf zone. Using data from a large-scale laboratory experim...
