摘要
本文根据东平水道沿程水文(位)站多年水文资料的分析,研究了东平水道上世纪60年代以来水文动力条件的变化。研究表明,东平水道在上世纪90年代以前,水文动力条件变化不大,但在这之后,发生了较大的变化,主要表现在:流量加大、水位降低、含沙量略有减小,悬移质输沙量增大、潮汐作用增强。
Based on the analysis of the data of many years from hydrographical stations along Dongping Waterway, this paper studied the changes of hydrodynamic conditions of Dongping Waterway since the 1960′s. The result revealed that the hydrodynamic condition of Dongping Waterway changed little before the 1990′s, but a lot after that, mainly in the aspects of increase of run-off, lowering of water stage, a little decrease of silt content, increase of transport of suspended silt, as well as strengthening of tidal action.
