Estimation of Hydraulic Conductivity And Transmissivity Of Quarternary Deposit Aquifer Using Vertical Electrical Sounding in Kertajati Majalengka West Java

The integration of geophysical data with direct hydrogeological measurements can provide a minimally invasive approach to characterize the subsurface at a variety of resolutions and over many spatial scales. The field of hydrogeophysics has attracted much attention during the last two decades. In this domain, the geophysical data inverted to geophysical models are interpreted in terms of the hydrogeology to serve as a basis for the definition of hydraulic models in the areas of interest. The hydraulic conductivity (K) value measured in a reference borehole has been combined with the electrical conductivity obtained from nearby Vertical Electrical Sounding data in the Kertajati confined aquifer. The resulting relation was interpreted with Dar Zarrouk parameters to infer the transmissivity variations at other vertical electrical sounding locations, where (K) values are unknown. The results indicate that the transmissivity values in the aquifer of interest vary from 553.935 to 14074 m2/day, and K varies from 38.48 to 203.776 m/day throughout the studied area
