Applying indicator-based geostatistical approaches to determine potential zones of groundwater recharge based on borehole data

► Potential zones of groundwater recharge are determined by IK based on borehole data. ► Combinations of subsoil infiltration and unsaturated soil permeability are used. ► IK has good functionality for determining groundwater recharge zones. ► The northeastern and southeastern regions are main groundwater recharge zones.
