Short summary
This study presents a multi-method framework assessing managed aquifer recharge (MAR) and extraction effects on groundwater dynamics in a typical temperate semi-arid fissured karst system, Jinan's Baotu Spring area. Results show MAR and extraction significantly influence karst groundwater levels and quality. The complementary techniques enhance the quantitative research accuracy and provide practical references for MAR in karst regions with similar hydrogeological conditions.
