Fine-Sediment Erodibility Characterization.
Abstract
This purpose of this technical note is to set forth a set of characterization test parameters or descriptors for evaluating the erodibility of fine-grained, cohesive sediments at open-water disposal sites. To establish or manage open-water disposal sites, assessment of the dispersion" of disposed materials from the site is often required. Dispersion includes both the relatively small losses of material carried away at the time of placement, and the main effect of erosion and transport from the bed under the action of waves and currents. The erodibility of fine-grained sediments depends on a number of parameters. Erodibility and the correlations between erodibility and sediment parameters are both highly variable and difficult to predict. Characterization parameters are a way to key in on erodibility. This technical note describes tiered laboratory tests which can be applied to provide some characterization parameters and. therefore, an indication of the erodibility of fine-grained dredged material. References are provided for test methodology.
