Scope: Review of geotechnical, hydrogeological and hydrological characteristics of existing dams, providing certification of dam safety
Client: UAE Ministry of Environment and Water
Period of assignment: 2010
Location: Dubai – UAE
In collaboration with: WRA
WRA teamed up with Reservoir Safety Services Ltd and Conser Consulting Engineers to carry out a review of four operational dams in the Hajar Mountains: Tawiyaeen, Wurraya, Sifuni and Showkah. Potential safety problems were highlighted relating to leakage, settlement and hydrology, listing action and remedial measures required to ensure that dam safety is maintained.
The WRA Assignment
The assignment included field reconnaissance and visits with the director of dams, Salim Akram, and a desk review of documentation at the offices of the Ministry of Environment and Water. Whilst Wadi Shawkah was full, Wadi Tawiyaeen was empty and over two metres of accumulated sediment was being removed from the reservoir basin. Certificates of dam safety were provided on completion of the report and inspection. The report summarised the findings of the inspection and included recommendations for operation, maintenance, supervision and monitoring of the reservoir that should be carried into effect as soon as is practicable.
Conference on Dam Safety
The team members also spoke at a conference organised by the client in the Municipality of El Ain, delivering papers on flood estimation for wadi catchments and the dams in UAE, and international practice in the monitoring and supervision of dam safety.
