Geophysical Investigations for Groundwater in Outita, Morroco, using ERT Method

Abstract

Abstract—Morocco is a country in semi-arid to arid climate. Rainfall is irregular in time and space. Surface water undergoes very large fluctuations due to the hydraulicity of the year. Hence, the use of groundwater resources that play a very important role in supplying water to rural populations and irrigation. In this context a geophysical survey was carried out in Outita. The interpretation of ERT profiles oriented West-East showed a horst and graben structure and revealed the existence of water-bearing formations at depths of around 300m. To determine the lateral extent of these formations, two ERT profiles oriented in the North-South direction were carried out
