The surgein tourismin the Parangtritis Coastal Area has resulted in a growing reliance on groundwater pumping. Understanding the hydrogeological conceptual model is crucial in comprehending the implications of groundwater exploitation. This study aims to establish a thorough hydrogeological conceptual model of the Parangtritis coastal area. The methodology involved collecting primary and secondary data to delineate study area boundaries and establish hydrostratigraphic systems, aquifer characteristics, and hydrological conditions. The study area has three hydrogeological boundaries: in the east, a no-flow boundary formed by steep hills; in the west and north, its river boundary by the Opak River; and in the south, a constant head boundary from the Indian Ocean. The hydrostratigraphic system of the study area comprises an unconfined aquifer that consists of fine sand and sandy clay, an aquiclude layer that consists of clay, a confined aquifer that consists of coarse sand, and an aquifuge layer that consists of andesite as the basement. Study area hydrological condition consists of parameters such as precipitation value of 2,132 mm/year, evapotranspiration value of 1,397 mm/year, runoff value of 344 mm/year, and groundwater recharge or infiltration of 391 mm/year. This hydrogeological conceptual model offers important information for groundwater modeling research in the Parangtritis coastal area.
