Groundwater Analysis and Numerical Simulation Based on Grey Theory

Abstract

In view of the deficiency of the traditional methods, based on the grey theory, GM (1, 1) model is established to predict the groundwater level. The proposed model was applied to predict the groundwater level in Xiaonanhai Spring. The prediction result was compared with that of the traditional method and the reported results in the Xiaonanhai Spring. It is indicated that the performance of the proposed model is practically feasible in the application of prediction of groundwater level and its application is simple.

“…The grey model is a powerful tool for forecasting the behaviour of the system in the future. It has been successfully applied to various fields since it was proposed by Deng [23][24][25][26][27][28][29][30][31]. In this paper we use a one-variable first-order differential grey equation, (1, 1).…”
