The relations between effects of sediment diversion and locations of the gate situated at the straight reach, concave bank, protruding bank in the main river are obtained.
Only deposition in river reach from Chenglingji to Wuhan after impounding of TGR?——Response on "Discussion on the flood control capacity of the middle Yangtze River after the impoundment of Three Gorges Reservoir"
By means of onedimensional water level and twodimensional flow state calculation,a comparative analysis of the water level and the flow state change at the river section before and after the Guijiang River Third Bridge built is made,the influence on flood control works in Wuzhou City by the bridge and its countermeasure is expounded.
The 1-D model has beencalibrated and verified against observed hydrological data and topographicalchanges from 1997 to 1999 in the river section between the two dams.
If the ice conditions were not considered,the water levels in the observed river reaches would be reduced by 0.1-0.4 m and the discharge capacities,increased by 30%-65%.
Based on the polymer and plastic analogy, the annual market for products that carry nano-components, including all computer chips, half of pharmaceuticals and half of chemical catalysts, will reach $1 trillion by 2015.
The conversion of CNB could reach 99.9%, and the dechlorination of chloroaniline (CAN) was less than 1.9% when catalyzed by Pt-Sn-B/CNTs and more than 8.0% when catalyzed by common hydrogenation catalysts.
However, in the river reach near the river knots, the water column distribution of flow current velocity does not fit the semi-log law, showing the irregular flow current pattern.
Concentrations of elements dramatically increase in the river reach near the Thermal Power Station (GRES) and next increase even greater in the lower reach of the river before its emptying into the Uryup River.
It is established that the boundary between the Kozhim (P1) and Kozhim Rudnik (P2) formations in the Kozhim River section is drawn inside a member, about 100 m thick, composed of six lithocycles of similar structure.
Modal value of the Au content in phtanites and clayey phtanites is three or four times higher than the clarke value in carbonaceous silicites and reaches anomalous values in some sections (e.g., Ogorodnaya River section).
As shown, the drastic reduction of the sediment runoff after the construction of two large reservoirs in the lower river reaches in the 1960s slowed down the delta protrusion and intensified the delta coastline washout.
The conclusion is made that the structural-functional organization of biocenoses in different river reaches is related with the environmental factors that form under the effect of this water.
