	6.	In this paper , some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data . the cross section of compound channel can be divided into four regions : the undisturbed region in main channel , the interactive region between channel and plain , the undisturbed region in flood plain and the boundary region . in the undisturbed regions , the distribution of longitudinal velocity along the depth has the feature of lograithmic . whereas , in the interactive region , the longitudinal velocity does not obey the logarithmic distribution law , but it can expressed as a revised logarithmic function by using a wake function . on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained . in the boundary region , the longitudinal velocity obeys the law of parabolic distribution . furthermore , according to the simplified diffusion equation , the transverse distribution of sediment concentration in the interactive region is deduced . the analysis is in good agreement with the measured data 本文根据漫滩水流的运动特点，将漫滩水流的复式断面分为主槽平衡区、滩槽交互区、滩地平衡区及边壁区等4个区，并给出了各区宽度的经验公式.根据滩槽交互区垂线流速分布的变化特点，提出了附加尾流函数的对数流速分布公式.在简化水流运动方程和泥沙扩散方程的基础上，对滩槽交互区内垂线平均流速及含沙量沿横向分布进行了理论分析，提出了反映滩槽水流动量交换强度的横向涡量粘性系数及横向扩散系数的表达式，得到了漫滩水流垂线平均流速及含沙量沿横向分布的解析解，并与实测资料吻合较好
	7.	In addition according to the comparison of typical floods the impact of floodplain morphology to the flood propagation was studied . no continuous water body in main channel and floodplain and the change of floodplain morphology and the increased flood detention capacity caused the time of flood propagation increasing and the flood types changing in abnormally 同时通过对典型洪水的对比分析，研究了滩地边界条件对洪水运行的影响，认识到由于主槽与滩地水体不连续以及滩地地形的改变，滩地蓄洪能力增大，造成洪水传播时间增长和洪峰峰型的异常变化。
	8.	First , according to measured data and literature , the river channel evolution rule and its reasons in the southern branch of the yangtze river are discussed from the perspectives of historic evolution , recent evolution and the tendency prediction of river channel evolution . besides , the local reservoir has been studied from the changes in thalweg and section as well as the calculation of local erosion and deposit . consequently , the stability and feasibility of reservoir construction in the river section are approved 首先根据大量实测资料及文献资料，就历史变迁、近期演变、河演趋势预测等方面，初步探讨了长江口南支河段河道演变规律及原因，并具体就深泓线的变化、主槽断面变化、局部冲淤计算等方面对拟建水库局部区域进行了分析，论证了工程河段建设水库的稳定性及可行性。
	9.	By the analysis and study , it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently 然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律，分析研究表明：建库前渭河下游主槽处于动态冲淤平衡状态，滩地处于微淤状态；建库后，渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的；潼关高程的抬升主要是由于三门峡水库的不合理运用造成的，近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。
	10.	Because the yili river belongs to plain broad and shallow moving river , the main channel changes greatly and swings to a large range , which leads to river crooked branching river type and s curved , many fork rivers , the river continent and the river beach in river center , alluvial shoal and beach . the width in some section of the river is up to about 3800m . in flood season it causes serious harm to farmland , factories , residents along two sides 由于伊犁河属于平原游荡性宽浅河流，主槽变化不定，摆动幅度极大，河道多呈弯曲分叉河型和s型弯道、多叉河、河心洲，河心滩和冲击浅滩及边滩，部分河段河床宽度达3800m ，洪水季节对河道两岸的田地，工厂，居民等造成极大的危害，素有“三十年河东，三十年河西”之称。
