Sustainable sediment management in reservoirs and regulated rivers: Experiences from five continents

open access: yesEarth's Future, 2014
By trapping sediment in reservoirs, dams interrupt the continuity of sediment transport through rivers, resulting in loss of reservoir storage and reduced usable life, and depriving downstream reaches of sediments essential for channel form and aquatic ...

Underestimated Microplastic Pollution Derived from Fishery Activities and "Hidden" in Deep Sediment.

Environmental Science and Technology, 2020
Fishery activities are an important source of microplastic pollution in coastal areas but have received little attention. The Beibu Gulf, a traditional fishing ground of China and the China-Indo Peninsula, was selected in this study, and the focus was on

Sediment Gravity Flows: II Depositional Models with Special Reference to the Deposits of High-Density Turbidity Currents

, 1982
Four principal mechanisms of deposition are effective in the formation of sediment gravity flow deposits. Grains deposited by traction sedimentation and suspension sedimentation respond individually and accumulate directly from bed and suspended loads ...

Improvement of the BCR three step sequential extraction procedure prior to the certification of new sediment and soil reference materials.

Journal of Environmental Monitoring, 1999
The Standards, Measurements and Testing Programme (formerly BCR) of the European Commission proposed a three-step sequential extraction procedure for sediment analysis, following extensive expert consultations and two interlaboratory studies. This scheme
