Abstract

Administratively, research area in located in Bergas District of Semarang Regency. Geographically coordinate located 704’48” – 7016’26” LS and 110020’10” – 110034’8” BT. On the function research to know about the geology and hydrogeologyfactor at boundary condition area of subbasin Bergas hydrology until water balance prediction, used to description method with six drilling from two companies, survey method with observation and measurement at field, and analysis method to water balance prediction with software, the kinds of software are Microsoft excel, Corel Draw X3, Arc.View 3.3 and Surfer. Research area denudasional landform, the kinds of gently sloping hill with elevation about 1200 m until 500 m, inclination about 25% until 40% and slope hill elevation about 500 m until 200 m, inclination about 10% until 20%. Litology physical influences transmisivitas level. It is devided by seven formation, the kind of andesite lava horblende formation, andesite breccia hornblenda formation, basalt flow formation, vulcano breccia formation, clay formation, basalt intrusive formation and andesite intrusive formation. According to aquifer productivity, the kinds of aquifer in which flow is both through fissures and interstices and aquifer of poor productivity and region without exploitable groundwater. Springs as indication of productive boundary with discharge water (springs as water sources). Groundwater basin is defined as an area with hydrogeology boundary, most of all occur hydraulic process are precipitation and run off. Groundwater basin of research area just part limited Ungaran Groundwater Basin called is a Bergas Sub Basin Groundwater. The aquifer system the kinds of aquifer are consolidated and unconsolidated system aquifer.
