Sediment cores contained admixtures of sand and gravel, silt, and clay-size particles (Table 1).Average clay content was highest (~22%) in Core 1 at the upriver sampling site; mid-river Core 2 contained the highest average silt content (~ 61%) and 19% clay content; Core 3 (estuarine location) contained the highest average total sand and gravel content (~ 36%).Cited by: (i) to evaluate the degree of contamination by comparing metal concentrations to sediment toxicity guidelines, (ii) to determine the distribution of overbank metal storage and assess geomorphic controls on that distribution, and (iii) to use particle-bound metals as tracers to estimate historical rates of floodplain sedimentation.
