Abstract
Gunungsewu is a largest Tropical karst terrain of Southeast Asia, about 800 km2
broad, and composed of around 45,000 hills of cones and domes, belongs to the territory of
Central Java, Yogyakarta, and east Java provinces. This area is now developed to be a national
geopark, therefore such facilities including the availability of fresh water sources must be
adequate. But in the matter of fact, Gunungsewu is always subjected to water scarcity especially
in every dry season. Aquifer of Gunungsewu is predominantly composed of reef limestones with
conduit flow typeand underground drainage system thatdischarge their water to Indian Ocean
through coastal springs. The occurrence of coastal springs are generally associated with unique
hydrogeologic phenomena and beautiful landscape.Due to very rough topography, steep cliffs,
and difficulty to be accessed, to explore the existence of groundwater discharge in coastal area,
fractal geometry analysis is applied. From the analysis, there is a correlation between the fractal
dimension value of coast shoreline and the existence of spring. Shoreline segments with fractal
dimension (D) higher than 1.30 is potential to the existence of coastal spring, whereas on the
segments with fractal dimension less than that, spring is absent. Baron is the biggest verified
coastal spring of Gunungsewu area, with flow rate 9000 l/sec average. The physical and
chemical quality of the water do not exceed the drinking water standard. This represents that the
existence of coastal springs in Gunungsewu area is actually potential to support the development
of geopark, as additional fresh water sources and as geosites or geo heritages.
Keywords Karst topography. Unique hydrogeology. Coastal groundwater discharge. Geopark
