Wadi Easal is located 3 km north Wadi Numayra, the purpose of the project is to provide water for irrigation and industrial purposes, flood protection, recharge, area development and environmental restoration. The consultancy services for the project consist of two distinct phases to make a clear decision on the project formulation. Phase (A) which is entirely devoted to prepare technical, economic, environmental and financial feasibility studies and preliminary design report for the construction of Wadi Easal Dam which aims to provide JVA with environmental, topographical, hydrological and geotechnical studies. Phase (B) comprises the preparation of the final design report, final tender documents and final drawings for the dam construction. Wadi Easal is a CFRD (concrete face rockfill dam) with a maximum height of 77 m and the catchment area draining to it is 62.71 km². The annual runoff is 3.15 MCM which includes the base-flow. The sedimentations in the reservoir are estimated in order to find out the life span of the dam for the 1^st 50% of its capacity which is more than 55 years and more than 118 years for the full capacity. The dead storage of the dam is estimated to be filled with sediments in 30 years operation assuming that there will be no flushing/sluicing of the reservoir. The spillway is designed for 1000 years peak flood of 230.6 m³/s with a peak flood released from the spillway with a surcharge head of 2.2 m with outflow of 229 m³/s. the sediment yield from the catchment is 41,347 ton/year.
