Abstract: Gravity dam construction by the roller compacted concrete method (RCC) has received widespread interest following completion of Shimajigawa Dam in Japan (1981) and Willow Creek Dam in the United States (1982). This paper discusses design considerations for Urugua-I Dam, the first RCC dam in Argentina. The dam will be a gravity concrete structure with centrally located overflow spillway, creating a reservoir of 1175 Hm**3 (952,000 af). It will have a maximum height above foundation level of 77 m (253 ft), crest length of 687 m (2253 ft), and volume of 600,000 m**3 (786,000 yd**3).
