PREDIKSI CADANGAN AIR TANAH DI DAERAH ALIRAN SUNGAI (DAS) CISADANE
ABSTRACT: Water is very
important for human beings. Sources of fresh water that can be used are only 3%
of the total water availability on earth, and 12% from that quantity are
soureces of groundwater. Groundwater is oneof the water resources that is very
important serve human needs, such as domestic, agriculture or industry.Geo-electric
is one of methods for groundwater investigation. The purposes of this research
are to identify lithology of soil layer and thickness of aquifer position on
research location, to determine hydraulic soilconductivity value, and to
predict the groundwater reserve potential in Cisadane Watershed. This researchwas
conducted in several steps, such as collected and analysis data. The processed
data was the secondarygeo-electrical data with schlumberger method. Calculation
of groundwater storage was performed by usinggeo-electric and Darcy’s law
approach. Aquifer thickness layer was obtained from the average content of aquifer
layer on research location, so it might represent the thickness of the aquifer.
From the calculation result, it was obtained that the predicted groundwater
storage was abaut 2.46 m3/second and 8.64 m3/second confined aquifer
respectively.
