Zeizoun Dam
The Zeizoun dam is situated on the Orontes river north of Hama in Syria and was originally constructed in 1996 with a capacity of 71 million³ and used for widespread irrigation in the Al-Ghab province.
On 4th June 2002 a failure occurred in the original dam which was completely destroyed and resulted in widespread flooding and damage. As part of the re-building program a new design with an extensive monitoring system is currently being implemented.
The new dam design includes a much deeper foundation which is intended to remove the weak strata identified as part of the reason for the failure. A grouting and monitoring gallery is included in the new design, which is located beneath the core foundation.
