SPATIAL AND TEMPORAL VARIATION IN SIZE AND SHAPE OF ...
adsorption of sedimentassociate contaminants and nutrients onto the surface of sediment. This thesis characterized the spatial and temporal variation in size and shape of sediment particles in the Tobacco Creek Watershed. A strong correlation between the particle size of suspended sediment and stream discharge was observed.
Spatial and temporal variability in juvenile bivalve ...
port of sediment and dispersal of juvenile bivalves in the Navesink estuary, New Jersey, USA to examine the contribution of spatial and temporal variation in current speed to dispersal patterns. Daily rates of juvenile bivalve dispersal were high and varied strongly across sites.
Effect of sediment spatial variance and collection method ...
Often only one sediment or one composited sediment is collected at a sample site, thereby preventing any determination of spatial variance. The significance of spatial variance and collection method on cladoceran toxicity and indigenous microbial activities was determined at a creosote contaminated site in the Little Scioto River in Marion ...

Recent SpatioTemporal Variations of Suspended Sediment ...
Water and sediment are two of the most essential elements in estuaries. Their product, suspended sediment concentration (SSC), is involved in hydrology, geomorphology and ecology. This study was focused on the spatial and temporal variations of SSC in the Yangtze Estuary under new situations after the closure of ~50,000 dams in the Yangtze basin, including the Three Gorges Dam (TGD) in 2003.
