| 摘 要： | 采用输沙量法对淮河干流吴家渡至小柳巷段实测水文资料完整的20年进行年际变化分析,河段总体表现为冲刷。枯水年份河段输沙基本平衡或微淤;中水年份冲刷年多于淤积年;丰水年份总体表现为冲刷。丰水年和中水年的总体冲淤趋势取决于汛期,枯水年非汛期对全年冲淤影响较大。系统分析了河段冲淤与吴家渡站来流量以及年均来沙系数的关系。

| Abstract: | Based on 20-year observed data,the interannual variation of deposition/erosion in Wujiadu-Xiaoliuxiang reach of Huaihe River is analyzed using sediment balance method.It is shown that this channel is generally under erosion state.In low flow years,the channel shows equilibrium or slight deposition.The erosion amout is more than deposition during medium flow years,and the channel exhibits erosion almost in all high flow years.The deposition or erosion in the reach during high flow years and normal years is m... |
