%X Understanding of groundwater flow and its relation to surface water is important to know about hydrology condition in the research area. It needs the understanding of groundwater level and its flow pattern as well as river water level. This research conducted by geological surface mapping completed by groundwater level and surface river water measurement. Result of research shows that groundwater flows to many direction toward Progo valley, at the central part of research area. Shallow groundwater levels vary at 100 – 835 m asl, whereas river water vary at 123 – 750 m asl. The type of relation between groundwater and surface water can be influent and effluent types. These types develop at many segments of streams. In some local area it can be found the same level of surface and groundwater. The aquifers dominantly are composed of sandstone or volcanic rocks/andesite breccia of Old Andesite Formation.
