Daftar Isi:
- The research was conducted in karst area, which is enclosed by Bribin Underground River Catchment which is administratively located in Gunungkidul Regency. The purpose of this study was to analyze the spatial and temporal variation characteristics of hydrochemistry on Bribin Underground River Catchment one -year. The method of this research is purposive sampling. Samples were taken representatively within upper, lower and leakage point of Bribin Underground River Catchment. Analysis on this research present the results with hydrograf analysis, chemograf analysis and descriptif analysis. The results showed variations of hidrochemistry on Bribin Underground River Catchment in the dry season and rainy season . In the rainy season the level of dissolved elements calcium (Ca2+) and bicarbonate (HCO3-) in recharge areas , upper, lower and leakage points decreased inversely proportional to the discharge, as well as the value of electroconductivity (DHL) . In the dry season value of conductivity (DHL) and dissolved elements of calcium (Ca2+) and bicarbonate (HCO3-) are increasing while discharge are decreased.
