The northern Batinah occupies approximately 12,150 km2 in the north of Oman Quaternary deposits and Neogene's upper Fats form the aquifer units. MODFLOW compatible MT3D was used for simulation development of the area. It can be concluded that: (1) The groundwater in the Batinah area generally flows from the south-west to the gulf of Oman in the north-east; (2) Recharge takes place through direct recharge from rainfall and wadi flow by about 902 ×10^3 ma/day; (3) The hydraulic conductivity attains a relatively wide range between 0.02 m/day and 78 m/day and 0.02 m/day and 60 m/day for the Quaternary and Fars respectively; (4) There is probably less potential for groundwater abstraction in the northern part of the area; (5) The water level decreased by about 6 m over 24 years and (6) The increase of salinity most likely due to a contribution of sea water intrusion from the gulf along the coast. It is recommended that: (1) automatic well control system should be installed to accurate measurements of abstraction; (2) further analysis under different future scenarios should be made and (3) formulate an integrated management plan for the basin. 展开更多
