Abstract
Rabigh, a coastal city along Red Sea, is situated within the downstream flood-plain area of an ephemeral 'Wadi' (river). The city is growing faster as an industrial city and consequently its needs have exponentially increased for the potable water. A research study mainly based on watershed and field investigation has been carried out for the assessment of water movement trend, natural behavior of water runoff and storage in the form of groundwater potential associated with the Precambrian crystalline rock and the Cenozoic basaltic lava-flow terrains in the Rabigh drainage basin. The main Rabigh drainage basin was extracted from the SRTM data by using relevant software. Considering the important outlets of large tributary networks, the basin was further demarked into three sub-drainage basins. The results of the watershed study indicate the complex hydro-morphological characteristics varying from sub-basin to sub-basin. On the basis of the end results, the prospective aquifers have been inferred associated with the fault/fracture zone(s) of the Precambrian rock terrain and/or basaltic lava-flows in the upstream Rabigh drainage basin and the strong runoff in the downstream coastline areas.
