摘　　要：近年来汾河下游防洪问题较为突出,主槽萎缩,河床抬高,河道过洪能力急剧降低,平滩流量大幅减小,从而造成中小水水位明显抬高。通过分析汾河干流水沙特性,对汾河下游河道来水来沙进行预测,结果表明2020年汾河下游河道主要水文站年平均淤积厚度为0.016～0.043 m。Flood control is always an acutely problem for the Lower Fenhe River in recent years. The flood discharge capacity of the channel and flow quantity below river beach is obviously decreased due to the shrunk of the main river channel and the heightened fiver bed. As a result, It directly caused the heightened of water level at medium or small scale flood flow obviously. From analyzing the feature of runoff and sediment influence to the Fenhe River main discharge, the paper forecasted runoff and sediment conditions for Fenhe River downstream and river evolution rhythmical under silt and sluice reaction.
