Simulation of Groundwater Flow in Porous Media Using the Finite Element Method (Case Study: Kabudarahang Aquifer)

Abstract

Abstract. Uncertainty in groundwater flow models is mainly due to the errors in the simulation of model values. In order to generate a mathematical model for groundwater flow, first, the input information in PMWIN software code was gathered and preceded. The obtained model was calibrated in two regimes under permanent and non-permanent flows. After conducting all these processes, the groundwater flow model of the Kabudarahang city were developed. In the calibrated model, parameters such as bedrock, K, , and T were corrected. Lowest and highest corrections were made on the amount of hydraulic conductivity and the bedrock, respectively.
