DESCRIPTION:Coastal karst aquifer of Lattari Mts. (~280 km2) supports drink
 ing water supply of the Sorrento Peninsula and Capri Island\, an over dens
 ely populated area in summer\, economically strategic for Campania region 
 (Italy) and outstanding environmental and cultural value. Based on in-dept
 h literature review and a GIS and R-based analysis of hydrological data\, 
 this study aims to reconstruct a novel conceptual hydrogeological model an
 d update the water balance to prevent excessive groundwater exploitation a
 nd deterioration from potential saline intrusion due to intensive withdraw
 als. A multi-method approach was used to assess a multi-scale groundwater 
 recharge\, integrating geological\, land use\, soil type\, cover type\, ve
 getation cover type and thermo-pluviometric data recorded with monthly and
  daily frequency by 24 meteorological stations over the period 2000–2023
 . In order to estimate the groundwater recharge\, three methodologies were
  applied\, two using the same water budget approach but different evapotra
 nspiration calculation methods (e.g. Thornthwaite-Mather and MODIS data)\,
  and a third independent approach based on the SWB (Soil Water Balance) mo
 del. Subsequently\, a comparison of groundwater recharge with natural outf
 low (Qoutsw) and withdrawals (Qoutw) was conducted using a geodatabase of 
 650 water point. At the aquifer scale\, the mean annual groundwater rechar
 ge estimated with Thornthwaite-Mather formula (5.21 m³/s) and MODIS (4.88
  m³/s) exceed those evaluated with SWB model (3.91 m³/s). The mean annua
 l groundwater recharge remains higher than water withdrawals in all cases\
 , although at the basin scale the current water withdrawals may be unsusta
 inable in the long term in some cases\, especially considering the interan
 nual variability of recharge. Results obtained can support decision-makers
  and stakeholders in promoting sustainable groundwater use and enhancing w
 ater system security in Campania's strategic economic area.
