Abstract EN
According to abrupt diagnosis of runoff, two methods, that is, moving approximate entropy and moving permutation entropy, are used to analyse the abrupt year of the daily river runoff from 1961 to 2006 at Lintong station of Wei River in Loess Plateau.
The runoff series are divided into 4 stages.
With the analysis of hydrological characters of different stages, we find that there are abrupt changes at the three years 1972, 1983, and 2002.
The result shows that moving approximate entropy and moving permutation entropy methods are useful tools for abrupt diagnosis of runoff.
The attribution of abrupt change at the Lintong runoff series is primarily due to the reduced precipitation, increased water conservancy project, increased water consumption of industry and agriculture, significantly decreased groundwater table, and increased evaporation.
