Does a change of irrigation technique impact on groundwater resources? A case study in Northeastern Italy

摘要: Abstract The Venetian plain is a densely populated area and one of the most economically competitive regions in Europe. Therefore, sustainable management water resources has to be accomplished preserve both social economic value this regional environment accordance with European policy directives. This paper presents analysis hydrologic hydrogeological balances high alluvial (approximately 790 km 2 ) highlighting some important peculiarities that could crucial for local policy. By focusing on importance different budget components, obtained results indicate irrigation relevant component aquifer recharge. Thus, Land Reclamation Consortia strongly influences Moreover, future scenarios (2071–2100) are performed taking into account changes climate inflow suffers decrease ranging from 18% scenario influenced by change 28% affected variations. In particular, recharge shows highest reduction due an increase evaporation, owing surface temperature, or methods. adopted fundamental concern.
