Abstract:

In this study a recent dam type, concrete face rockfill dam (CFRD), its design and behaviour is overviewed. The design features of Gökçeler Dam are introduced as a case study. Selection of concrete face rockfill type for Gökçeler Dam Project is discussed together with the other two alternatives, namely earth core rockfill (ECRD) and roller compacted concrete (RCC) dam. Gökçeler Dam type selection as concrete face rockfill dam is also verified by an economic analysis conducted calculating internal rate of return for all alternative types. In cost analysis a currency independent defined unit cost (DUC) is specified to verify the time independent validity of the economic analysis.
