This new edition in 2010 cites 280 dams and updates the data and recommendations of the first two 38 and 78 Bulletins. It reviews the new information and practices that have appeared in the meantime, which include application of geomembrane as the only watertight element in fill dams, in Roller Compacted Concrete dams, as external joints on Roller Compacted Concrete dams, as underwater repair of dams on gravity dams and on Roller Compacted Concrete dams.Table of contents:
