Abstract
In this article, the potential for artificial groundwater recharge of Wadi Al-Butum catchments area - Jordan is studied, using geoelectrical resistivity surveys and hydro geochemical methods with the aim of storing some of surface water during flood events times to be recharged in the groundwater as an essential part of integrated water resources management. The results of geoelectrical surveys show the existence of potential zones of alluvial deposits to store and recharge the groundwater aquifers. The hydro-geochemical modeling results show an overall upgrading of the original groundwater quality could be expected.

Jordan is located in an arid to semi arid lands, and it is considered among the scarcest water resources countries in the world

Summary
Jordan is located in an arid to semi arid lands, and it is considered among the scarcest water resources countries in the world. It is estimated that the total population in Jordan will be around 12 millions by 2020 [4] This will add more pressures on the existing water resources in the country leading to a massive decrease in per capita to 85 m3·capita–1·year–1 by 2025 [4]. One alternative to water sustainability crisis occurring in arid land is groundwater artificial recharge. The major source of water for recharging groundwater aquifers in arid and semi-arid zones is wadi runoff [6]. [8,9]) In this present study, hydro-geophysical investigations including vertical resistivity sounding surveys and hydrogeochemical modeling were carried out with the aim of studying the potential for artificial groundwater recharge in Wadi Al-Butum catchments area
