Abstract: Based on field survey and investigation,the characteristics of flow and sediment of broad shallow rivers in Xinjiang province are analysed ,and the characteristics of flow shifting are expounded. The results show that broad shallow rivers in Xinjiang have characteristics of low flux ,steep gradients and high flow velocity. In addition,those rivers have characteristics of coarse bed materials,high sand load ,quick change in scour and fill and obvious shifting banks.The characters differ from thos

Key words: Xinjiang, broad-shallow shifting rivers, water flow, sediment

摘要： 基于现场观测和实地调研,分析了新疆宽浅变迁性河流的水流泥沙特性,阐述了宽浅变迁河流的变迁特点. 结果表明新疆宽浅变迁河流具有流量小、坡陡流急、床沙粒径较粗、含沙量大、冲淤变化快、变迁明显等特点,与内 地河流相比存在显著的差异,这对新疆桥涵设计及河流整治具有一定的理论和实践指导意义
