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. The work was supported by a review of satellite imagery to assess catchment conditions and new developments downstream of the dams. Sifuni Dam was inspected in 2010, and a return visit was made to assess the causes of high level of seepage through the armoured embankment. 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. The assignments were carried out by Paul Holmes, Ian Carter and Andy Sheerman-Chase, with the support of the client’s and CONSER engineering staff.
Talks on Dam Safety in Fujairah and Al Ain
The team members also spoke at a conference organised by the client in Al Ain Municipality on 6 December 2010, delivering papers on flood estimation for wadi catchments and the dams in UAE, and international practice in the monitoring and supervision of dam safety. Further presentations were made at a seminar in Fujairah for MOEW engineers, on dam safety and international standards, on 28 November 2011.
