Application of Chaos Time Series Method in Groundwater Table Prediction
Wei Jie · Journal of Water Resources and Architectural Engineering · 2011
Applying G-P(Grassberger-Procaccia)arithmetic,C-C arithmetic(the improved method) and Wolf method based on phase space reconstruction method, Lyapunov exponents are distilled from one-dimension time series of underground water table in Fanxian County,Hualong District and Nanle County of Puyang City.The results indicate that this time series possesses the character of chaos. Then,an adding-weight one-rank local-region forecasting model is developed for the prediction of underground water table.The results show that the model is feasible and valid for the short term prediction of the time series of underground water table.
