Aquifer system and groundwater potency in coastal area of Kretek, Bantul Regency, Indonesia

The existence of groundwater in coastal areas really needs attention because of its vulnerability to sea water intrusion. Utilization and good management are needed to maintain its sustainability. The purpose of this research is to determine the aquifer system in the study area and to calculate the...
