…Viet Nam has one of the largest dam systems in the world, comprising more than 7,000 dams. Approximately 640 of these dams are classified as medium and large dams, and a large percentage of the Vietnamese population is potentially at risk from dam failure flooding, particularly if operation of dams is poorly considered.
In a collaboration between Viet Nam and New Zealand governments since 2012 a disaster risk reduction project to improve dam management and community safety throughout a river basin has been developed by dam safety experts from both countries. Known as the Dam and Downstream Community Safety Initiative (DDCSI) the project has developed a Dam Safety Methodology for dam owners and managers to identify and quantify the natural hazards and assess the risks associated with their dams and develop options to mitigate these risks.
The Dam Safety Methodology will be used to (i) identify and prioritise works and operational improvements needed to improve the safety of a dam, and (ii) identify where Disaster Risk Management can be improved for communities downstream of a dam. This will enable dam managers and owners to target specific improvements to safely manage existing reservoirs or in the planning and design of future projects…
