Abstract

This research was conducted in the Seropan underground river in the Gunung Sewu karst, Gunung Kidul Regency. This study aimed to identify some of the flood hydrograph properties of the Seropan underground river to characterize the karst aquifer. A water level data logger is installed to detect underground river water level fluctuations during the recording period. In addition, time series discharge measurements at minimum, average and maximum flow are carried out to formulate a stage-discharge rating curve. Thus, the hydrograph of the underground river during the measurement period can be determined. After that, several flood hydrographs were selected to calculate the diffuse flow recession (Kb), fissure flow (Ki), conduit flow (Kc), time to peak (Tp) and time to base flow. The analysis results show that the Seropan underground river responds fairly quickly to rain events (Tp = 3.5 h). Then, the calculation results show the value of the recession constant (Kb = 0.995; Ki = 0.863; Kc = 0.666), which means that the Seropan Cave underground river still has a large enough base flow deposit with a fairly slow release (Tb = 45.3 h). This base flow deposit is reflected in the minimum discharge during the dry season above 300 ltr/second.
