Maurizio Polemio has expertise on hydrogeology, hydrology, and engineering geology aspects of studied phenomena, and is pursing the quantitative characterisation of the following, including in situ measurements, surveys and monitoring, especially in the case of coastal carbonate aquifers; hydrogeological conceptualisation; water resources management in Mediterranean regions, quality degradation and vulnerability of groundwater; quantity degradation of groundwater resources due to overexploitation or to climatic change; hydrogeological characterisation and monitoring of aquifers and slopes; numerical modelling of groundwater flow and transport, and for slope stability analysis; geostatistics and hydrological statistics of hydrogeological time series; the relationship between rainfall and recurrence of damaging hydrogeological events as landslides and floods; protection against impacts of climate change and adaptation solutions; coastal aquifers and saltwater intrusion; groundwater resources and management.
