Modelling the interactions between groundwater and the underground infrastructures using MODFLOW-USG and ArcGIS Pro: the case study of Milan metropolitan city

Since the beginning of the 1990s, following an intense phase of industrial dismantling, the area of the current metropolitan city of Milan (440 Km²) has been subject to the rise of groundwater level that has generated problems of interference with the underground infrastructures (parkings, metropolitan lines, etc.). The growth in the use of three-dimensional models for groundwater flow, combined with an exhaustive database of the underground employment by the infrastructures, allows today to be able to predict and to manage the effects of changes in the hydrogeological system on the anthropized one. This work aims at better understanding the interactions between the underground infrastructures and the groundwater flow.
