International Commission on Large Dams (ICOLD) - The Physical Properties of Hardened Conventional concrete in Dams
Committee on Concrete Dams, 1991 - 2008, 262 pages
The purpose of this Bulletin (145) is to provide a comprehensive treatise on the physical properties of hardened conventional concrete for dams, refreshing the partial information contained in some out-of-date ICOLD Bulletins, giving ana account of new approaches and exaamining also some important properties not included in the previous Bulletins.

New approaches, considering points of view still not explored, may introduce useful tools in the study of Hydrodynamics and the related transport phenomena. The details of the flows and the properties of the fluids must be considered on a very small scale perspective. Consequently, new concepts and to...

159 pages , April 11-12, 1997 In the 1980s proposals for large dams began to be fundamentally questioned by locally affected interests and global coalitions of environmental and human rights groups (for example, Sardar Sarovar). In the 1990s this has resulted in a succession of calls for a moratorium on World Bank funding and reparations for those affected by construction of large dams (for example, the 1994 Manibeli and 1997 Curitiba Declaratio...
