Abstract

The research area is located at the central of West Progo Hills, in Yogyakarta and Central Java
Province, Indonesia. It is hard water area, but there are some springs appearing from Jonggrangan and Old
Andesite Formations. These formations consist of hard, compacted Tertiary rocks which have dissected by
some lineaments of structure or morphology. The lineaments may control to springs characteristics, involve
their appearance, frequency and discharge. Field observation has been done to collect springs data. The small
discharge has been measured by water gauge and stopwatch directly, while the big ones have been measured
by river channeling measurements. On the other hands, lineaments were determined from Landsat image,
SRTM and topographic map as well as from field. The result shows that lineaments in Old Andesite
Formation develop in many directions followed by spring appearance, in random location. Springs in
Jonggrangan Formation mainly appear in NE-SW direction in accordance with the azimuth of lineaments
almost in SW-NE direction. The springs of both formations usually appear controlled by individual
lineaments, indicated by coefficient correlation of 84% for the relationship between distance of spring –
lineament and the numbers of springs. The density of lineaments also control of springs appearance (r = 62%
for cross dots of fractures and r = 51% for length). The distance between lineament and spring to discharge
rate of springs seems no influence indicated by r2 = 0.0495. It means that lineaments influence to spring
occurrence in their density and distance characteristics.
