In this paper ,the anaiysis on the hydrologic and sediment conditions and channel characteristics of the Qinghe braided reach is discribed. The emphersis is given to discuss the bed process regularity. Accordingly, the principle, methods and engineering measures for the channel regulation have been pro posed.
The influence of water and sediment irrigation on the river channel siltation and erosionis related to the original river siltation and erosion situation,the ratio of the water irrigation andsediment diversion,and river channel characteristics,and others.
To solve the water problems of this region, some key proposals are made: 1. The hydrological and channel characteristics of the mainstream of the Yangtze River Delta and the causes and regularities of their variation be clarified.
To elucidate the formative cause for the decrease in sediment for the sediment transferring function,the temporal variation in F_(s) has been compared with the temporal variations in a number of drainage basin factors,including drainage basin factors and river channel characteristics.
A study on the characteristics of channel and fluvial processes in the Lower Reach of Changjiang River has been carried out based upon the geographic investigation, analysis of runoff, sediment and fluvial processes, measurement of channel and shoals such as water depth, width of river and radius of curvature, and study on shoal changes in 110 years.
In order to explore harness scheme, layout, measurements and parameters concerned of the project, which are appropriate for the characteristic and the evolvement law of the watercourse of Ningxia section of the Yellow River, the study on the experiment of the scoured pit of the dam buttress and runoff of the root rock of Ningxia section of the Yellow River is of important theoretical meaning and practicable value.
The writing briefily introduce the specificatiom property of rive section, the deformation′s charater of every section and its main regulated measures and benefit.
Mainly affected by operating level of the Plant, fluctuating backwater area appeared characteristics of reservoir region during low water period, and those of river channel during flood period in consequence of upstream incomings of water and sediment.
An optimization problem is proposed, aimed at minimizing a video distortion metric based on sequence-dependent parameters, and transmission channel characteristics, for a given wireless network infrastructure.
Scanning electron microscopy and micro-computed tomography were used to show that 3D scaffold architectures were honeycomb-like with completely interconnected and controlled channel characteristics.
A description of light heavy-ion fusion, taking into account both entrance-channel characteristics and compound-nucleus properties, is derived within a unified theory of nuclear reactions.
Presynaptically the rule depends on the NMDA channel characteristic, and the model predicts that an increase in Mg2+ will attenuate the STDP curve without changing its shape.
We explore the important case when the channel characteristic is not available at the transmitter but the receiver knows (tracks) the characteristic which is subject to Rayleigh fading.

Hanjiang River, one of the biggest branches of the Yangtze River, is braided at the middle stretch and meandered at the lower. Danjiangkou water control project is completed in 1968. On the basis of analysing features of the river at the middle and lower Hanjiang River, the erosion process and the development trend after the project completed is emphasized in this paper. At the same time, the effect of this change on the navigation channel is discussed.
On the basis of the analysis of the relationship between the hydro-dynamic and the patterns of loads transportation (PLT in short), this paper describes that in the mouth region of Yangtze River where the tidal effect is apparent, under the actions of the runoff, tidal current, and the coriolis force, there are six typical modes of the bed load transportation, i.e. the reciprocating transportation mode, the clockwise transportation mode, the accumulation mode, the mode of the circulating anti-clockwise tran...
