Ganjiang river trail channel is affected by both upstream water and the backwater effect of Poyang Lake during the flood season. The study of the water level changes has guiding significance for river flood control and shipping. Based on the measured data from 1990 to 2019 at the hydrological station in the Ganjiang river trail channel, this paper adopted the Mann-Kendall trend test and the Pettitt test to analyze the trend of the characteristic water level during the flood season (flood season and backwater of Poyang Lake season). The results show that the water level of the Ganjiang river trail channel had a significant downward trend. The interannual variation of the water level during the flood season was relatively uniform, while it showed a fluctuating shape during the backwater of Poyang Lake season. The mutation years were all around 2002. The main reason for the decline of the water level during the flood period is the erosion of the riverbed. The downward trend of the riverbed has slowed down significantly after 2013, so water level during the flood period stabilized after 2016. The water level during the backwater of Poyang Lake season is mainly affected by the erosion of the riverbed, and the change of the downstream water level will also have a certain impact.

赣江尾闾河段汛期受上游来水与鄱阳湖顶托的双重影响,研究其汛期水位变化对河道防洪和航运有重要的指导意义。为此,根据赣江尾闾控制性水文站1990~2019年的实测水文资料,采用Mann-Kendall趋势检验和Pettitt检验方法对赣江尾闾河段汛期(河洪及湖洪)特征水位的趋势性及突变性进行分析。结果表明,赣江尾闾河段河洪期和湖洪期特征水位均呈显著下降趋势,河洪期水位年际变化较为均匀,湖洪期水位年际变化呈现出波动状,两者的突变年份均为2002年左右。河洪期特征水位下降的主要原因是河床下切,其下切趋势于2013年后明显减缓,故河洪期水位在2016年之后趋于稳定。湖洪期特征水位主要受河床下切影响,下游水位变化也会产生一定的影响。

赣江尾闾河段汛期受上游来水与鄱阳湖顶托的双重影响,研究其汛期水位变化对河道防洪和航运有重要的指导意义。为此,根据赣江尾闾控制性水文站1990~2019年的实测水文资料,采用Mann-Kendall趋势检验和Pettitt检验方法对赣江尾闾河段汛期(河洪及湖洪)特征水位的趋势性及突变性进行分析。结果表明,赣江尾闾河段河洪期和湖洪期特征水位均呈显著下降趋势,河洪期水位年际变化较为均匀,湖洪期水位年际变化呈现出波动状,两者的突变年份均为2002年左右。河洪期特征水位下降的主要原因是河床下切,其下切趋势于2013年后明显减缓,故河洪期水位在2016年之后趋于稳定。湖洪期特征水位主要受河床下切影响,下游水位变化也会产生一定的影响。

Ganjiang river trail channel is affected by both upstream water and the backwater effect of Poyang Lake during the flood season. The study of the water level changes has guiding significance for river flood control and shipping. Based on the measured data from 1990 to 2019 at the hydrological station in the Ganjiang river trail channel, this paper adopted the Mann-Kendall trend test and the Pettitt test to analyze the trend of the characteristic water level during the flood season (flood season and backwater of Poyang Lake season). The results show that the water level of the Ganjiang river trail channel had a significant downward trend. The interannual variation of the water level during the flood season was relatively uniform, while it showed a fluctuating shape during the backwater of Poyang Lake season. The mutation years were all around 2002. The main reason for the decline of the water level during the flood period is the erosion of the riverbed. The downward trend of the riverbed has slowed down significantly after 2013, so water level during the flood period stabilized after 2016. The water level during the backwater of Poyang Lake season is mainly affected by the erosion of the riverbed, and the change of the downstream water level will also have a certain impact.
