     Advanced pumping technologies contributed to increase of groundwater utilization all around the world for several purposes such as agriculture, potable water supply, industry etc.. Due to the benighted use of groundwater, irreversible damages have occurred in phreatic surfaces. To recover the decreased groundwater level, water retaining structures are widely used for aquifer recharge. In this seminar, discussion will be carried out about the feasibility stage design of groundwater recharge of Wadi Keed dam (Bahla, Sultanate of Oman) which was assessed considering hydrogeological conditions and geotechnical parameters of dam location and proximity. For the design, field, office, and laboratory works had been conducted. Field works consisted of a drilling program, excavation of trial pits and in-situ tests such as falling head permeability tests and Lugeon tests. The laboratory works had been performed on the core samples handled from the drill-holes and the soil samples obtained from trial pits. In context of office studies, the results obtained from field and laboratory works had been evaluated and the recharge dam was designed based on the geotechnical properties and hydrogeological conditions of the dam location. Accordingly, Wadi Keed dam is optimized to facilitate groundwater recharge based on the geotechnical and hydrogeological data. It is predicted to percolate 400,000 m3 water per year for recharging the Bahla aquifer and this percolation will uplift 8 m of the phreatic surface around Bahla City.
