Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were...

Research in fluvial geomorphology in China during the past 30 years was mainly along the lines of valley geomorphology, channel geomorphology, estuaries and deltas. A great amount of systematic investigations has been carried out in the fields such as valley evolution history and features of Changjiang River(Yangtze River) and Huanghe River(Yellow River) and their relations with geology, climate, neotectonic movement, etc. Field evidence suggests that the course of Sanxia(the Three Gorges) of Changjiang were formed as early as at the end of the Cretaceous, and then the Yangtze valley was sharply cut down from the uplifting Exi planation surface, and took shape of a series of deep gorges into limestone strata. Investigations have also found that the upper reach of Jinsha River near Dengke once flowed southeastward into Yalong River. Recently the study of river valley geomorphology of the Xizang Plateau reveals that Yaluzangbu River is an antecedent river and that the Daguaiwan gorge in the east of it is neither an elbow ot capture nor a tributary flowing westward to join the Indus as were formerly taken to be. Research into channel geomorphology developed somewhat later, but has made rapid progress. A grade separation system has been put forward for the classification of channel patterns, and attentions given to the dynamic characteristics of the formation and evolution of channel patterns by using C_v(variation factor of the peak discharge) and ρo/ρp(the ratio of incoming sediment concentration to the sediment carrying capacity in a channel) as indexes to indicate the stabilities of different channel patterns and the mutual transformations among them. By analyzing many rivers with heavy sediment concentration, a wandering index has been derived. Rivers having the value of greater than 5 are called shifting and less than 2 unshifting. In the middle and lower Changjiang, the latest research of meanders and relatively stable channel patterns has had some results. Observations and simulation experiments con the fluvial processes of the channels above and below reservoirs reveal that the channel of Huanghe below Sanmenxia Reservoir, after baving been washed by clear water, still remains shifting for a long time, and the headward silting end of Weihe channel above the reservoir stretches out or draws back within a certain limit. The investigations of deltas point out that since the Quaternary the mouth of Changjiang has been extending southeastward and that there exist imbricate fossil deltas under the water. As for the Huanghe delta, it is evident that since the diversion of the river course in 1855, a new delta with an area of 5,450 km~2 has been built up. Penetrating research has also been made on the geomorphological features and processes of the evolution of Qiantang River. Field survey discovers that the main source of Changjiang is Tuotuo River rising in Geladandong snowberg, and that of Huanghe is Kariqiu River originating in Geshigeya Mountain of the Bayankala Mountains.

三十年来我国河流地貌的研究主要为河谷地貌、河床演变和河口三角洲。其中,河谷地貌研究提出了长江三峡在白垩纪末已经形成,其后从鄂西期夷平面下切于石灰岩层内而形成一系列峡谷。发现金沙江上游在邓柯附近曾向东南流入雅砻江。论证了雅鲁藏布江横贯喜马拉雅山脉的为先成河,并非由于河流袭夺的结果。河床演变的研究提出了游荡指标>5为游荡,<2为非游荡。以C_v和ρ_o/ρ_p两值作为河型稳定和转化的指标。对三门峡、丹江口等水库上下游的河床演变进行了观测和模拟试验。研究了长江、黄河和珠江等三角洲的形成演变,提出了新的见解。经过实地考察发现长江的正源为沱沱河,发源于各拉丹冬雪山;黄河的正源为卡日曲,发源于巴颜喀拉山脉的各式各雅山。

Weihe River is one of the tributaries flowing into the Sanmenxia Reservoir. The Lower reach of the Weihe River is a meandering alluvial river with very flat slope. It was in a state of quasi equilibrium in a long term.The confluence of the Weihe River with the main stream of Yellow River is at Tongguan, 113 km upstream from the dam site. The stage at Tongguan may be considered as a local base level of the lower Weihe River.Since the impoundment of the Reservoir,backwater deposits extended upstream in a...

Weihe River is one of the tributaries flowing into the Sanmenxia Reservoir. The Lower reach of the Weihe River is a meandering alluvial river with very flat slope. It was in a state of quasi equilibrium in a long term.The confluence of the Weihe River with the main stream of Yellow River is at Tongguan, 113 km upstream from the dam site. The stage at Tongguan may be considered as a local base level of the lower Weihe River.Since the impoundment of the Reservoir,backwater deposits extended upstream in a rapid rate as a result of the raise of the bed elevation of Tongguan. After the change of the mode of reservoir operation and the subse quent reconstruction of the outlet facilities of the dam, the bed elevation of Tongguan had lowered to some extent. The Weihe River had undergone selfadjustment according to the variation of the bed elevation of Tongguan and the incoming water and sediment flow. L rge floods with hyperconce ntration of sediment took an active part in the flushing of the backwater de-Posits. However,serious deposition have been observed during small flood with hyperconcentration of sediment. In the Process of adjustment, the terminal of backwater deposits of the main channel travelled to and fro in both directins and that of the flood plain extended upstream gradually. The compositions of the bed material became finer and the channel cross section became narrower and deeper. After many years of adjustment the sediment transport and flood concarrying capacity have recovered to a state prior to the construction of the dam.The development of backwater deposits in both main channel anb the flood plain are gradually becoming stabilized.

本文简要地阐述了三门峡水库修建前后,泾、渭河水沙基本特性、渭河下游河道特征、冲淤变化,以及潼关局部侵蚀基准面的升降、渭河口拦门沙消长对渭河河道演变的影响,着重分析了建库后渭河下游河道比降、河床形态、河床物质组成诸因素的调整过程,以及渭河下游滩、槽淤积末端延伸的基本物理图形和延伸规律。指出河床调整及淤积末端发展的趋势。对影响淤积延伸的因素进行了初步的探讨。

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.

汉江是长江最大的支流之一,中游为分汊性河段,下游为婉蜒性河段.丹江口水利枢纽工程于1968年建成·本文在分析建坝前汉江中下游河道特性的基础上,着重讨论建坝后河道的冲刷调整过程以及河床演变的趋势.同时,还讨论了这些变化对航道的影响.
