水库纵向淤积形态分类研究

On Classifying of Deposition Feature in Profile of Reservoirs

我国江河泥沙含量大小不一,北方河流含沙量大,尤其是西北地区含沙量很高,南方地区江河含沙量一般较小。河流上修建的水库都要淤积,但根据水库所处地理位置及所处流域的自然条件的不同、水库运用方式不同,其淤积纵剖面不同。对我国水库淤积纵剖面形态分类研究状况和成果进行了全面的综述。内容包括公式的形式、公式采用的资料范围、公式的判别标准及对每个公式的简单评价。

In China,sediment content in rivers is different.Sediment concentration is high in the north,and is much more great in the northwest especially.It is lower in the south.Each reservoir is deposited.The deposition features in profile are different.That is caused by geographical position of the project,natural condition of the river basin,operation way of the reservoir,and etc.Researches in classification of deposition feature in profile is dealt with.
