Modelling suspended sediment flow in arid upland basins
A conceptual basin model of the instantaneous unit sediment graph was developed for sediment graph prediction from arid upland basins by routing mobilized sediments through a series of linear reservoirs. The sediment graphs generated by convolution of the instantaneous unit sediment graph compared reasonably well with the observed ones for four representative arid upland sub-basins in the Luni ...
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 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 کاملNumerical Modelling Sediment-Bacteria Interaction Processes in the Severn Estuary
Faecal bacteria exist in both free-living and attached forms in estuarine waters. The deposition of sediments can take faecal bacteria out of the water column and to the bed. The sediments can subsequently be re-suspended to the water column, which can then lead to re-suspension of the faecal bacteria of the attached forms back to the water column. Therefore, the fate and transport of faecal ba...
متن کاملNonlinear acoustical properties of suspended sediment
Maritime advances during recent years have shown the importance of and the need for development of ultrasonic methods for the investigation of the transport of suspended marine sediments in rivers and in coastal regions. Two main acoustical procedures have been developed and used for the investigations of suspended sediment qualities during the laboratory studies, (1) high frequency resonance b...
