The determination of the permeability of unconfined aquifer by fourier series expansion: A case study in the biggest arid area in China — Xinjiang

Groundwater mathematic model is a basic and effective measurement in terms of analysis, prediction and management in groundwater resource. Conductivity, a parameter of aquifers, is of great importance for the establishing and calculation of any groundwater mathematic model. The purpose of this paper is to find an effective and economic method to get the conductivity, via introducing the idea of the tide into the identification of hydrogeological parameter. Fourier series expansion and superposition principle of harmonic waves are used and the Kaerdayi section beside the Tarim River in Xinjiang, China is taken as an example. The permeability is obtained and the certification is carried out. This study indicates that it is a convenient method of solving permeability, which can be utilized in future research.
