Abstract:Theoretical and experimental studies were undertaken to gain insight into physical parameters controlling the flocculation and settling properties of mud flocs in the Changjiang Estuary, China. The Rouse equation is applied to vertical profiles of suspended sediment concentration to determine the bulk mean settling velocity (w s ) of sediment suspended in the Changjiang Estuary. Both in situ point-sampled and acoustically measured profiles of suspended mud concentrations were fit selectively. The calculated settling velocities w s mainly ranged from 0Ð4 to 4Ð1 mm s

“…Changjiang Estuary with a water surface area of 90 km 2 , Annually, on average, over 9.24×10 11 m 3 fresh water from the river empties into the East China Sea with mean sediment load of 4.86×10 8 ton (Chen and Zong, 1998;Chen et al, 1999). During the past few decades, the Changjiang detail region has been one of the most important economical areas in China.…”

Surface sediments and bivalves were collected from the Changjiang Estuary in December 2003 and November 2004, respectively. Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) in these samples were measured with high-resolution chromatography (HRGC)/High Resolution Mass Spectrometer (HRMS). The concentrations of total PCDD/Fs and toxic equivalent (TEQ) were 169.83±119.63 and 0.81±0.36 pg/g dry weight (dw) in sediments, and 580.33±240.17 and 7.24±3.65 pg/g dw in bivalves. The homolog compositions of PCDD/Fs were similar among samples, the most abundant congener was octa-chlorinated dibenzo-p-dioxin (OCDD) and then octa-chlorinated dibenzofuran (OCDF) and 1,2,3,4,6,7,. The herbicide pentachlorophenol (PCP) and sodium pentachlorophenol (Na-PCP) were proved the main source of PCDD/Fs in this area.

“…To facilitate local navigation, the Deepwater Navigation Channel (DNC) was built, 92 km in length and 12.5m deep. Although the channel comprises two dikes of nearly 50 km each, as well as 19 groins built to increase speed along the DNC, silting is still an issue, and dredging maintenance is greater than originally predicted [44,55,[64][65][66][67].…”
