Innovative technologies for the sustainable management of water resources: the WARBO (WAter Re-BOrn) project

The WARBO project will facilitate the regulation of water artificial recharge (AR) and determine how to respond to the need to safeguard, protect and enhance water and land ecosystems. The project will focus on sites with AR problems hosting ecosystems of community interest where urgent measures are needed to fight against water scarcity and to develop protocols able to specify how to manage recharge activities. The protocols concerning direct (hydrogeological, geochemical and isotopic) and indirect (geophysical and remote sensing) surveys will be finalized and applied to two main macro-areas. The first is the Friuli plain (NE Italy), with the aim of identifying the shortand long-term effects of the recharge of highly permeable aquifers in order to mitigate the lowering of piezometric levels and the degradation of the forested areas impacted by a gradual shift of the springs towards lower altitudes and to estimate the water savings that could be achieved through the reclamation and use of grey water in the ZIPR test site (San Vito al Tagliamento, Pordenone). The second is the southern Po Plain in the Copparo area (Ferrara, northern Italy) in order to assess the effectiveness and the issues connected with recharge activities in salinised aquifer inland characterized by medium-low permeability and to estimate the effectiveness of phytopurification systems and the improvement of biodiversity. The aims of the WARBO project are: the integration and updating of the CAMI-LIFE database to improve existing knowledge and to better evaluate the hydrogeological and geochemical evolution of aquifers; the updating of the conceptual model and identification of test areas; the application of innovative hydrological 3D models implementing state-ofthe-art numerical procedures to solve partial differential equations (as finite elements, mixed finite elements, finite volumes).
