Abstract:
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.
