DescriptionDams and Capacity of Artificial Reservoirs

This map shows a global databank of 633 large impoundments from a series of world dam registers published by ICOLD and IWPDC (ICOLD, 1984; 1988; IWPDC, 1994; 1989). Attributes of the dam and reservoir dataset were derived from the ICOLD database include: dam name, year built, river name, nearest city, province, country, continent, dam type, length, volume of dam body, reservoir capacity, reservoir area and latitude and longitude.

Interpretation

The costs and benefits of large dam projects have been debated and are highly controversial. Although large dam projects can provide much needed water supplies and power generation to a region they also pose environmental, social and economic concerns. Large dams have displaced millions of people worldwide many of whom have not been satisfactorily resettled or compensated. In addition, dams have fragmented 60 percent of the world rivers leading to irreversible impacts on riverine and terrestrial environments. The economic benefits of dams are not always realized when compared with costs.

Background

This dataset was developed in support of the analysis outlined in Vörösmarty et al., 2003. Details of the global dam and reservoir database development are detailed in this publication.
