| Summary: | Beton karst spring is located in the Ponjong sub District Gunungkidul Regency, at the
western part of Bribin undergorund river catchment area. The purpose of this study are: 1) to
know the variations of rainfall and discharge in the research area, 2) to know the
characteristics of the physical water quality of Beton spring and 3) to determine the
relationship between the variations of the rainfall toward the discharge and the physical
water quality of Beton spring. This study uses survey methods and the techniques of data
collection using sample by purposive sampling. The variables are rainfall (the depth and
intensity), spring discharge and physical water quality of spring (EC, T, TDS, turbidity). The
data analysis is conducted graphically and descriptively to explain the relationship between
the variations of rainfall to the discharge and physical water quality of spring. The results
show the rainfall has variations include the pattern, events and the amount of rainfall. Beton
spring has high discharge variations. The physical water quality of the spring meets to the
water quality standards according to the Government Regulation number 82 years 2001. The
strong correlation between rainfall variations to the discharge and the physical water quality
of Beton spring can be seen clearly. It is reflected from the high value of R2. |
