Sediment Stabilization and Permeable Barriers with Organoclay
Organically modified clays, also called organoclays, have found acceptance as components of sediment and soil stabilization admixtures and as a components of permeable barriers. Sediment stabilization consists of blending organoclay with the sediments of a river, lake or estuary in an effort

Going By the Flow Using Acoustics To Track Stream Sediment
Research Unit's laboratory in Oxford, Mississippi, as well as in nearby Goodwin Creek. "Accurate determinations of the rate of sediment movement by streams are necessary because sediment can fill reservoirs and reduce their capacities," says Kuhnle, the project's leader. "It can fill channels and cause

Environmental Particle Analysis
of sediments it may well give important information about the origin and distribution of material through the action of tidal, wind and other flows. Often the examination of the size of pollen granules present in the sediment can provide important information about a site (such as what types of plant life were
