Sediment Transport
Contaminated sediment, By Daoyi Chen, Department of Engineering, University of Liverpool
Contaminated sediment has accumulated in rivers, lakes, estuaries and coastal waters due to several centuries of industrial activities. Pollutants penetrate the surrounding surface waters and groundwater; thus, posing a potential threat to the water quality and ecosystem. A major area of interesting for this session is the transport of pollutants which has taken place through a number of different processes, such as, sediment re-suspension, diffusion, pore water movement and surface/subsurface water interaction. Field studies and engineering schemes which tackle contaminated sediments are also welcome. Discussions are also encouraged on further issues, such as, the absorption/desorption of pollutants to sediments, bio-accumulation of pollutants into aquatic organisms and food chains, as well as, sediment sources of nutrients for algal blooms and red-tides.
