Groundwater is a vital source of water for the needs of human, animals, and plants, not least in Bogowonto Downstream Watershed, Purworejo Regency. Bogowonto Downstream Watershed is a region which near with international airport development planning in Temon District, Kulonprogo Regency, Special Region of Yogyakarta. Along with this international airport development planning is absolutely necessary studies about the use of groundwater allocations in support of the region development. This research uses Remote Sensing and Geographic Information System (GIS) technologies to make groundwater potential mapping. The imagery which used in this research is Landsat 8 imagery to interpret land parameters, such as rock type, landform, lineament, soil texture, and landcover. The other datas which used in this research is Geology Map, Rupabumi Indonesia Map (Topographic Map), and Soil Map as references of identification. The method used in this research was scoring method in which each parameters rated in accordance with the effect of the groundwater potential resulting land unit for analysis of groundwater potential. The result from this research are groundwater potential map distribution in Bogowonto Downstream Watershed, precisely in Bagelen, Purwodadi, and Ngombol Districts. The higher potential of groundwater located in flat area, which is in Districts of Purwodadi, Bagelen, and Ngombol. The medium potential of groundwater located in coastal area, which is in Districts of Puwodadi and Ngombol. The lower potential of groundwater located in hilly area, District Bagelen. |
