Estimation of groundwater potential using the electrical resistivity method - Wenner Array

Abstract

Groundwater as a water resource has now become a complex national issue. Therefore, due to excessive groundwater abstraction, it is necessary to minimize the negative impact. This research aims to estimate groundwater level distribution and its possible use at the Faculty of Engineering of the University of Jember. A total path length of 392 meters was investigated. Field data was collected using a resistivity meter with the Wenner configuration method. In addition, the data obtained from the measurements were processed using RES2DINV software. The results showed that the distribution of groundwater lies at depths between 25.3-39.7 meters. Meanwhile, the potential use for aquifers is classified as moderate. This is based on the classification of groundwater potential, which indicated that the layers of soil at the site contain alluvium plains and coarse-grained to medium gravel and sand, with the addition of clay.
