GROUNDWATER TABLE AND LANDSLIDE VULNERABILITY IN VARIOUS LANDFORMS IN THE PRAMBANAN DISTRICT
GROUNDWATER TABLE AND LANDSLIDE VULNERABILITY IN VARIOUS LANDFORMS IN THE PRAMBANAN DISTRICT

Summary/Abstract: The Prambanan District (Bokoharjo, Wukirsari, and Sumberharjo, and Sambirejo Subdistricts) has specific groundwater condition. This area is not only exists andesite and tuff but also stretch fault that give special groundwater behavior characteristics. The aim of this research is to define groundwater table in various landforms in correlation with landslide vulnerability. Field survey measurement was used to define groundwater table in various landforms. Groundwater table sample in various landforms was taken by transect profile or route in each landform. Then, landslide vulnerability in correlation with groundwater table was determined using deterministic approach. Based on the results, it shows that groundwater table is following morphology of landform. Moreover, groundwater in this area gives specific characteristic due to its rock structure. Moreover, landslide vulnerability is low to modest levels due to the condition of groundwater table.
