Session 1 – Groundwater resource management
(session supported by the ENeRAG H2020 Project)
Conveners: Prof. Giovanni Pietro Beretta (Università degli Studi di Milano), Eng. Giovanni Formentin (Tethys s.r.l.), Dr. Marco Rotiroti (Università degli Studi di Milano-Bicocca)
Groundwater is the largest source of freshwater in Italy, as in many regions worldwide. Groundwater quantity and quality should be preserved in order to guarantee the fulfilment of the different water needs by humans and ecosystems. Groundwater resource management has to balance the increasing demand of water with groundwater resources availability in terms of quantity and quality.
Topics covered by this session are: water resources assessment, climate change impacts on groundwater resources, groundwater/surface-water interactions, groundwater monitoring, groundwater quality and quantity protection, groundwater governance, groundwater flow modelling, background levels derivation, managed aquifer recharge, saltwater intrusion.
Session 2 – Fractured rocks and karstic systems
Conveners: Prof. Francesco Fiorillo (Università degli Studi del Sannio), Dr. Francesca Lotti (Kataclima S.r.l.), Dr. Livia Emanuela Zuffianò (CNR-IRPI Bari)
In fractured and karstic systems the groundwater flow depends on the presence of joints (faults, fracture zones, bedding and foliation planes with slow flow, acting as reservoirs) and conduits (characterised by quite rapid flow, and then acting as drains). The hydrogeological conceptual model of these systems may span from continuum to discrete depending on the working scale and fractures/conduits distribution.
Topics covered by this session are: hydrogeology and flow dynamic of fractured and karstic systems, mountain springs and mineral/thermal water resources, tracing tests, numerical modelling of fractured and karsts aquifers, relation between rainfall and spring regime, speleological investigation, subterranean streams, gas-enriched water.
Session 3 – Contaminated sites
Conveners: Prof. Domenico De Luca (Università degli Studi di Torino), Dr. Michele Pellegrini (Syndial S.p.A.), Dr. Ivana La Licata (Politecnico di Milano)
Investigating the distribution, transport and fate of anthropogenic contaminants into aquifer systems are key aspects in contaminant hydrogeology. The main goals in contaminated site analysis are to address the origin of the contamination, assess transport processes and forecast the fate of contaminants, determine strategies for environmental protection and remediation of contaminated environmental matrices. To this end, a multidisciplinary approach matching hydrogeology, hydrogeochemistry and microbiology is preferred.
Topics covered by this session are: water quality characterization, transport and reactive transport modelling, remediation technologies, batch and field experiments, isotope techniques, microbiological techniques, monitoring.
Session 4 – Urban Hydrogeology
Conveners: Dr. Rudy Rossetto (Scuola Superiore Sant’Anna Pisa), Dr. Massimo Marchesi (IT2Europe S.r.l.), Dr. Stefania Stevenazzi (Università degli Studi di Milano)
Urban hydrogeology deals with the hydrological cycle and its changes, both in terms of quantity and quality, within urbanized areas. For instance: groundwater recharge/discharge clearly differs from that in natural systems; groundwater can affect underground structures and pollution problems can be caused by point and/or non-point sources related to urban activities and underground utilities.
Topics covered by this session are: urban water cycle, groundwater fluctuation due to land and water use changes, emerging pollutants, geothermal heat pump (GWHP-GSHP) systems, heat transport, groundwater flooding, groundwater and underground utilities, groundwater and urban structures.
