Abstract

Water is the most of basic needs of living things. The need of water tends to increase for daily life, industrial agricultural, and livestock. Due to of population growth, the need of residential areas has increased. This mean that water consumption increased so the amount of water has become limited. This study aimed to identifying the depth of groundwater in Tanah Mas area, North Semarang, Semarang City. This study used the VES resistivity geoelectrical method with Schlumberger configuration. In Schlumberger configuration, the voltage electrode distance is much smaller than the current electrode distance. Research data were taken by Resistivity meter Naniura NRD 22 S in five locations with stretch length of 200 meters. Data were processed using Microsoft Excel, Ip2win,dan Rockworks software's. The result of this study were found rock layers below the surface consists oftop soil, clay and sand layers. The groundwater were found is a shallow aquifer which is believed to be in the sand layer from 9.92 to 37.70 meters depth. 2D and 3D form were modeled to explained the distribution and depth of groundwater.
