Özet
Under favour of advancing pumping technologies, groundwater is utilized all around the world for many purposes such as agriculture, potable water supply, industry etc. Due to the benighted use of groundwater, irreparable damages are occurred in phreatic surfaces. To recover the decreased groundwater level water retaining structures are widely used for aquifer recharge. In this study, feasibility stage design of groundwater recharge Wadi Keed dam (Bahla, Sultanate of Oman) was assessed considering hydrogeological conditions and geotechnical parameters of dam location and proximity. Within this context, field, office, and laboratory works had been conducted. Field works consist 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 dam location. In this regard, Wadi Keed dam is optimized for a groundwater recharge purpose based on the geotechnical and hydrogeological data. It is predicted to percolate 400 000 m(3) water per year for recharging the Bahla aquifer and this percolation will uplift 8 m the phreatic surface around Bahla City.
