Protection of the city of Sur from flooding
New Fulaij dam
Context & Issues

Sur, a city with a hot desert climate (on average 80 mm of rainfall per year), was severely damaged by two cyclones in 2007 and 2010, which produced rainfall in excess of 300 and 400 mm in the space of 24 hours. 

Following studies performed by Sogreah’s Dams and Hydropower Department in 2008-2010, the Ministry of Regional Municipalities and Water Resources (MRMWR) decided to embark on the programme of works, including construction of a fill dam.

Project characteristics
  • Fill dam: 26.50 m high, 1,100 m long
  • Concrete flood spillway: 30 m high, 140 m long
  • Four large silt removal outlets, one water intake
  • Works to canalise the main bed of the watercourse: 9 km, 3,000,000 m3 of earthworks
