Evaluation of Dredged Sediment as a Silt and Clay Source for Artificial Tidal Flats

Clay Minerals as Indicators of Sediment Source in Tidal Estuaries of Long Island Sound

-Clay minerals were used as indicators for determining the source of sediment in recently dredged harbors along the north shore of Long Island Sound. Amount and characteristics of clay minerals in sediments from the dredged channels were compared to their amount and characteristics in the surrounding soils and in sediments from Long Island Sound. Clay minerals in sediments from the channels wer...

Tidal Flats and Muddy Seafloors

The objectives of our studies in FY09 are to collect observations of currents, waves, and bathymetry on tidal flats, and to develop, test, and improve models for tidal-flat processes and for mud-induced dissipation of waves in shallow water. Specific goals relating to tidal flats are to: Investigate the relative importance to the circulation of riverine and tidal flows, and Estimate the bottom ...

Determination and fractionation of sulphur in a contaminated dredged sediment.

Conversion of sulphur compounds in reduced, contaminated sediments that are brought in upland conditions may largely affect the potential mobility of heavy metal contaminants. We applied selected methods for the determination of total sulphur and sulphur fractions in a contaminated sediment in the reduced state and after gradual drying and oxidation during 1 month. Dry ashing, followed by ion c...
