ABSTRACT
In the last 50 years, large changes in the runoff processes of the Luanhe River Basin have
exacerbated the scarcity and spatiotemporal variability of water resources. It is both theoretically and
practically important to study the characteristics, trends and periods of runoff changes in the Luanhe
River Basin. In this study, the moving average method, the Mann-Kendall test and wavelet analysis
are applied to analyze the evolution of the natural runoff of the Luanhe River using runoff data for
1959-2018 at the representative stations in the Luanhe River Basin, namely, the Goutaizi, Sandaohezi
and Luan County stations. The results show that the runoff volumes at the three stations decreased for
1959-2018, including abrupt decreases at the Goutaizi station in 1969 and at the Sandaohezi station
in 1976. The Luan County station exhibited a significant increase in runoff after 1997. The significant
periods of variation in the runoff for the upper, middle and lower reaches of the Luanhe River are
28 years, 27 years and 30 years, respectively.
