A Comparative Study of VMD-Based Hybrid Forecasting Model for Nonstationary Daily Streamflow Time Series

Table 1

The characteristic parameters of daily streamflow at the Wushan and Weijiabao hydrological station (m³/s).

Station	Data range	Max	Min	Mean	Sx	Csx
Wushan	2001/1/1∼2014/12/31	643	0.03	11.17	17.87	11.48
Weijiabao	2001/1/1∼2014/12/31	2190	1.98	57.09	137.38	6.45

Max, Min, Mean, S_x, and C_sx denote the minimum value, maximum value, average value, standard deviation value, and skewness coefficient of streamflow series, respectively.
