DESCRIPTION:Groundwater plays a crucial role in the water cycle and in sust
 aining life and human activities\, and can help alleviate hydrological dro
 ught periods serving as a buffer reservoir. Groundwater sustainability\, h
 owever\, relies on a delicate balance between recharge and discharge\, in 
 which humans play an important role\, with influences on groundwater depen
 dent ecosystems. Agricultural Managed Aquifer Recharge (Ag-MAR) can be an 
 adaptation measure to drought periods and expected climate change effects 
 on water resources. As part of the Interreg CE project MAURICE\, an off-se
 ason irrigation practice is proposed in Lombardy as a climate change adapt
 ation strategy\, storing surface water into aquifers in periods of exceeda
 nce (autumn/winter) using the existing irrigation network’s canals as a 
 "natural" infiltration system.\nIn the case study area\, a great number of
  typical Northern Italy lowland springs\, called “fontanili”\, is pres
 ent\, used since the XIV century to irrigate fields while generating biodi
 versity hotspots right in a urbanized area. In the past decades\, they hav
 e been largely abandoned and endangered by infrastructures and decreasing 
 groundwater levels. Their relationship with groundwater still holds some u
 ncertainties related to their interaction with the aquifer along their cou
 rse and their influence on the surrounding groundwater system\, which coul
 d hinder the performance of measures like the proposed Ag-MAR.\nThis work 
 presents numerical models in MODFLOW that\, with increasing complexity\, r
 eproduce a single lowland spring’s behavior based on in-situ observation
 s and literature\, considering pros and cons of the different methods. The
 n\, the lowland springs have been implemented in a larger scale model\, to
  simulate scenarios assessing their response to the implementation of off-
 season irrigation. Results bring more light to these unique systems’ beh
 avior and show concrete and successful possibilities of modeling them and 
 applying Ag-MAR also in their presence.
