Consultancy Service for the flood protection of Quriyat City in relation to the Wadi Mailass basin

Cyclone Gonu (2007) and Peth (2009) have caused a hundred of casualties in Oman country with injury for houses, facilities, goods and assets. The overall objective of the project was to conduct feasibility study and prepare detailed design for construction of the most economically advantageous engineering solution that would protect the flood prone areas of Quriyat and of the whole catchment (villages of Mukhadah, Hayfadh and Siya), from floods and avoid losses of lives, damages of properties, delay and disruption in life.
The protection of Quriyat was achieved with a dam and its reservoir that can damp the floods of Wadi Majlass and release discharges that can pass through the town and reach the sea without flooding. The protection of Mukhadah, Hayfadh and Siya was achieved mainly with wadi arrangements and dikes that increase the hydraulic section available for flood discharge.
