Gomal Zam RCC Arch-Gravity Dam in Pakistan

Gomal Zam Roller Compacted Concrete (RCC) Arch-Gravity Dam is up to now the only arch-type RCC dam in Pakistan. In the selection of dam axis and type, the local topographical and geological conditions were intelligently used to create the largest reservoir with the minimum dam volume. During the construction, several innovative technologies were applied. This paper highlights the notable structural features and innovative construction technologies.
