Based on the field data of recent twenty years, the problems such as the effects on channel degradation and aggradation, flow structure and the configuration of river, etc,have been studied, and the conclusions may be drawn as follows:1. For hyperconcentration flow, the bed of Weihe River degrades at high discharges, and aggrades a...             本文根据渭河20年的实测资料,就高含沙水流对于河道冲淤、水流结构和河道平面形态的影响等问题,进行了初步分析研究,得到如下几点认识: 1.渭河下游有大水高含沙量冲刷,小水高含沙量淤积的特点; 2.由于十多年来渭河水少沙多,下游出现河床“粗化”现象,增加了河床的抗冲性; 3.在天然河道中,高含沙水流不仅改变垂线流速分布,而且也改变垂线平均流速分布,在弯道最大流速偏离凹岸趋向凸岸,使凹岸淤积凸岸边滩冲刷; 4.渭河在含沙量高达500～600公斤/米~3的条件下,垂线流速分布服从对数分布规律。但它几乎近似于直线,而且没有发现有流核区. 文摘来源          Based on the investigation of natural reaches of the Middle and Lower Yangtze River andthe classification of their channel patterns, this paper analyses the geometry criterion of various channel patterns in detail, and obtains the different relations between geometry elements and the transform-ing conditions. Finally, it is stated that geometry analysis plays an important part in river regulation.             在作者曾对长江中下游河道平面形态进行统计和河型分类的基础上，本文对不同河型的形态指标作了进一步分析，获得了不同河型的平面形态诸因素之间的关系及河型转换中的形态条件，初步阐述了形态分析在河道整治中的作用。 文摘来源          In this paper the geological background, geomorphological characteristics and channel evolution of Jingjiang Tributary in the past 100 years are discussed.
