DescriptionCohesive sediment erosion differs significantly from coarse-grained, non-cohesive (sand) erosion phenomena. Non-cohesive sediment erosion can generally be quantified based on applied shear stress and grain size distribution. Cohesive sediment erosion is related to these factors and to sediment bulk properties, including bulk density, mineralogy, pore-water chemistry, and organic content. Although it is known qualitatively how many of these parameters may affect erosion, a priori quantitative methods of relating cohesive sediment erosion to these bulk properties are not available. Methods have been developed to determine a site-specific relationship between erosion rate and shear stress using rate results obtained through sediment sample testing on the U.S. Army Corps of Engineers' (USACE) Sedflume. The objectives of this study were to extract a total of 28 sediment cores 30-60 cm deep from 14 locations along the Passaic River in order to: Measure the erodibility as a function of depth for different shear stresses using the Sedflume; Measure and analyze bulk density, organic content, and grain-size distribution data vs. depth for the Sedflume coring sites; Qualitatively analyze the response of erosion rates to changes in bulk properties.
