The Regulation of braided stream with heavy sediment load calls for a complete change in river regime of a stream course running hundreds of kilometers long. This is only possible by modifying the hydrograph and the sediment production rate of the watershed and by changing the boundary conditions of the stream channel. The construction of reservoir in the upstream basin upsets the equilibrium conditions of the river downstream of the dam, and a change in regime is expected. The braided river, after gradually losing its wandering intensity, will transform into a meandering pattern. At the beginning of the adjustment, the shifting of the main current still exists. The channel will be deepened by the passage of water with much smaller sediment concentration. Yet, on the other hand, the recedence of the bank lines under the attack of the ever-shifting current tends to widen the channel. The eventual modification of the cross-sectional form of the degrading reach depends on the interaction of these two types of forces. At low and medium stages, it appears that the deepening of the channel has gained the upper hand. After the passage of a larger flood when the water overflows the flood-plain, a rapid widening of the channel will take place instead. In as much as the recedence of the bank lines is a threat constantly in existence, every effort should be made to cut down the flow released from the dam to a value smaller than the bankfull discharge of the downstream channel, and bank stabilization works must be started immediately after the completion of the dam. The control of the mean-water channel and the protection of the bank lines should be proceeded hand in hand, with the former as the main measure. It is proposed to modify the river course into a succession of smooth bends such that the thalweg will be fixed along the concave side of the bend and low sand banks formed on the other. By using a smooth curve to guide the flow, the jetties and training walls will be subjected to a force evenly distributed along the bend, and this is beneficial for their maintenance. The protection length of the concave bank depends on the radius of curvature of the bend and on the variability of the flow. According to the experiences obtained from one of the sandy rivers in China, the ratio of protection lengths upstream and downstream of the apex of the concave bank is 2 to 3. In the degrading reach, it is sufficient to stabilize the concave side of the bend only. In the transition and aggrading reaches, underwater jetties should also be built along the bank line at the lower half of the convex side of the bend.

在多沙河流上修建蓄水拦沙水庫以后,下游游蕩性河道将逐漸向弯曲性轉化.如下洩清水不超过下游河道的平滩流量,則河床将以下切为主;如水流继续不断漫滩,則河道将逐漸展寬。固定中水河槽是保护滩地,加速河道調整过程的重要途径,应尽量利用已有节点,增加节点数目,并逐步改善节点外形,使其具有曲度适当的弯道型式。文中根据多沙河流的經驗及模型試驗結果,对河湾平面尺寸、护岸导流工程的布置及結构进行了初步探討.

The present paper gives a new solution method of 2-D cascade flow, in which the free streamline boundary conditions can be satisfied. This is a cross-iterative calculation method between two correlating flow fields. The 2-D subsonic flow problem for calculating the upstream and downstream regions of the ordinary blade cascade, the splitter and the tandem blade cascades is discussed from an unified viewpoint. The computer program can be available for these three cases.For calculating the splitter and the tandem blade cascades a physical condition of minimum disturbance of the flow field is proposed, so that the flow division of the two blade channels formed by the splitter blade or the splitter stream surface can be calculated.Some results of numerical examples are presented and compared with the experimental data, the comparison has proved preliminarily the validity of both the presented method and the proposed physical condition for determining the flow division. Some useful thoughts are also given concerning the aerodynamic design of the splitter blade rotors.

This article is the research report of the total sediment transport model test of Gezhouba Project on the Changjiang River (Yangtze River). It is the first large-scale engineering project on the River. There is no precedent to go by in engineering design, and all the problems of the engineering layout should be determined and solved by sediment transport model tests.The studies have covered seven years, from 1974 to 1980.According to the theory of sediment movement andv the data obtained from sediment model tests, the sediment problems of the project have been studied extensively, such as the programme of layout, the flow regime for navigation and the realignment of waterway, the location and quantity of scouring and deposition of sediment, the distribution of grain size and concentration of sediment entering into hydroelectric station, especially the scouring and deposition upstream and downstream of the navigation canals. Emphasis has been laid on the solution of some key technological problems of the main hydraulic structures. Meanwhile, constructive amendments have been submitted to the engineering project in all aspects, all of them have been put into effect.
