Modification of input parameters to conceptual model of the Ghoochan basin using GMS model

A groundwater model can be used to understand the mechanisms influencing groundwater flow and transport of dissolved groundwater sensitivity to stress might predict, predict the future, knowing the path, estimating the pollution, environmental risk assessment, etc. In this paper, the necessary data for aquifer modeling and validation were prepared and the appropriate conceptual model was developed from the aquifer. After that Ghuchan aquifer has been simulated by GMS model in a steady-state condition. In spite of the number of observation well (23 rings) and shape of aquifer and lack of enough information such as hydrodynamic coefficients, the bedrock, etc the modeling results indicated that the model able to well simulate changes in groundwater levels. Bedrock correction coefficients returned water from wells, and hydraulic conductivity obtained from the model.
