Preliminary identification of areas suitable for Sustainable Drainage Systems and Managed Aquifer Recharge to mitigate stormwater flooding phenomena in Rome (Italy)

This paper proposes a preliminary and large-scale survey methodology to identify areas suitable for indepth analysis the application of Sustainable Drainage Systems Managed Aquifer Recharge. These techniques are frequently applied increase natural infiltration capacity water into ground their effectiveness depends on local hydrogeological morphological characteristics. The study area is city Rome where aim mitigate problems related rainwater which, in case extreme events, struggles infiltrate ground, overloads undersized drainage systems, floods urban space.The proposed method involves GIS geospatial permeability outcropping lithologies, digital elevation model, piezometric levels aquifers. To zones, characterised by high level that would confer volumetric possibly store even large quantities water, without triggering possible table rise, were identified. Data divided classes indexed compare overlap them. Furthermore, final result was compared with flooding phenomena soil map Rome. results performed show conditions apply SuDS MAR widespread. geological setting permeable lithologies many places an effective potential allow subsoil reach first available aquifer.
