Abstract:
Groundwater resources constitute the most important part of human water available to human beings. Reducing precipitation and droughts in recent years has faced the challenge of reducing the underground water cycle. Numerical modeling of groundwater is an important tool for managing water resources in aquifers. The purpose of this study was simulation of groundwater level fluctuations using GMS and GIS software in the Jafariye plain aquifer of Qom province. The mathematical model that combines the MODFLOW 2000 and ArcGIS 10.3 groundwater model, simulates the groundwater level using a finite difference numerical method. To conduct this research, the required information including the location of the aquifer boundary, ground level altitude, ground level, position and rate of harvesting from the wells, the position and level of water level in the wells, the hydraulic conduction layer and nutrition, in the information system environment Geographic (ArcGIS 10.3) and arrived at the model. After designing a conceptual model and determining boundary and primary conditions, the simulation was carried out under stable conditions and then the model was calibrated. Finally, a map of quantitative changes of groundwater level of Jafariye plain was made in GIS software in 1993, 2003 and 2013. The results showed that the groundwater level decrease in the year 1993 was equal to -0.05 meters, in 2003, it was -0.26 meters and in 2013, it was -7.7 meters, indicating a sharp drop The water level is continued through extraction from the groundwater storage of the Jafariye Plain aquifer.
