CALCULATION OF AQUIFER DISCHARGE IN ACEH INDUSTRIAL ESTATE AREA BASED ON VERTICAL ELECTRICAL SOUNDING DATA

Abstract

Planning for groundwater requirements in the Aceh Industrial Area needs a study of the potential existence and types of groundwater. This study analyzes the potential and flow rate of aquifers using the Wenner configuration Vertical Electrical Sounding (VES) method. This method was applied to identify subsurface layers, determine the position and thickness of aquifers, and calculate groundwater flow rates using Darcy's law. Data acquisition was conducted at six measurement points using the ARES instrument. The number of electrodes used is 4, with 2 as current electrodes and 2 as potential electrodes. The electrode spacing applied was 2 meters. The resistivity raw data obtained was processed using EarthImager software to generate a 1D subsurface model.
