Modeling of Groundwater Mound Due to Artificial Recharge: A Case Study of Ghalangan Area, Shahrekord Plain

Groundwater mounding is the phenomenon that was occured due to local infiltration water to soil and rising of water table. Among benefits of this phenomenon could mention to preventing of infiltration of salt water to aquifers in coasts، saving and Maintenance of water in subsurface for using in future and preventing of declining of groundwater head in some areas. The creation of saturation zone، decreasing of recharge velocity، groundwater quality problems due to reduction or lose infiltration ability to under unsaturated zone، the possibility of internal flow or discharge of surface water، decreasing of building fortifications and wet foundation are among of disadvantages of this phenomenon. Despite the advantages and disadvantages of this phenomenon، the study of this field is important. So analytical and numerical solutions have offered for simulating and better understanding of it. In this regard in the present study، was written a computer code in the Matlab programming language based on analytical solution. The developed results using PMWIN software was validated for Ghalangan region in Shahrekord plain in Chaharmahal and Bakhtiari province. Results showed that the accuracy of model in simulating of groundwater local mounding is acceptable.
