Abstrak/Abstract Pindul cave located in Gunungkidul Regency, Gunungsewu Karst Area, Indonesia has a unique characteristic which is dominated by surface rivers (allogenic recharge) and groundwater (autogenic recharge). The main purpose of this study is to analyze temporal variation of flood water hydrogeochemistry in Pindul Cave. Water sampling for flood hydrogeochemistry analysis is taken in the wet season for three selected flood events. Parameters of hydrogeochemistry analysis consist of major dissolved element (Ca2+ and HCO3-); conductivity; total dissolved solid; SI calcite; log PCO2; and pH. The result shows that there was correlation between flood discharge and hydrogeochemistry parameters. The hydrogeochemistry of flood events in Pindul Cave typified by a low value of calcium and bicarbonate and high CO2 gas content in water that indicated the dillution by precipitation processes. Pindul Cave also show the negative value of calcite during flood event which mean that groundwater is unsaturated, so it becomes aggressive towards calcite. According to the flood water hydrogeochemistry characteristics, Pindul Cave is dominated by conduit flow from the large-fracture that already developed.
