Abstract
En 中文
• HCA analysis for assessing groundwater dynamics at local scale • Hydrochemical and isotopic data from 44 piezometers, rainfall and river waters • HCA analysis revealed 3 groups of groundwater distributed between 2 recharge sources • Main recharge by Rhône of groundwater along the eastern boundary of the alluvial aquifer • HCA revealed historical polluted area and the aquifer responsiveness to extreme events
