The groundwater budget: A tool for preliminary estimation of the hydraulic connection between neighboring aquifers

摘要

Highlights?Groundwater budget calculation of an aquifer exploited for conjunctive purposes.?Identification of a water deficit (40% of total outflows).?Comparison between the deficit and the long-term monitoring of the aquifer.?Evaluation of the external deep groundwater inflow.?Proposal of a conceptual model of the aquifer recharge.AbstractGroundwater management authorities usually use groundwater budget calculations to evaluate the sustainability of withdrawals for different purposes. The groundwater budget calculation does not always provide reliable information, and it must often be supported by further aquifer monitoring in the case of hydraulic connections between neighboring aquifers.The Riardo Plain aquifer is a strategic drinking resource for more tha
