The thesis starts with the aim of making a model capable of calculating the infiltration during a fractured medium as a operate of the quantity of fractures, their inclination, and the slope of the ground. The model was created with the Modflow software package that was believed to be the foremost appropriate for its ability to simulate the hydrogeology of the study area with larger precision. The area of the Coricancha mine in South American nation was used as the study area; the goal was to use the info of atmospherical precipitation and infiltration water, which the mine has, to calibrate the model once created.
