The History of the World Register of Dams


The History of the World Register of Dams


The World Register of Dams of ICOLD is a fizzy fountain of information for design, construction, scientifical work and statistical work and statistical evaluations. The last version includes more than 62,000 large dams according to the definition of ICOLD (height at least of 15 m above the foundation or above 5 m with a capacity above 3 million of m3). For each dam more than 45 information are given, amongst them geographical data, data of the dam, the spillway, the reservoir, the stakeholders as well as important environmental data…


It is interesting to look at the stages of the creation and evolution of the world register of large dams corresponding to the ICOLD criteria.
