This study presents the results of prediction of rockfill Dam settlements obtained by analysing factotrs influencing Dam settlement. Several predictions such as empirical equations suggested by lawton & lester, Sowers, Soydemir & Kjaernsli, and Speeddie are compared with the observed of settlement for post-construction rockfill Dam. (1) In construction method, dumped rockfill-membrane dam show the highest settlement, compacted rockfill-mmambrane dams show the smallest settlement. (2) Lawton & Lester's equation is considerably fitted with the observed in central core dam but higher than the observed value by 17%. (3) In the case of Sloping core Dam, the predicted in largely, differ from the observed ; Soydemir & Kijaernsli's small than the predicted by 50%, other equation's high than the predicted by 67%. (4) Sower's is very similar with the predicted value of dumped rockfill-membrane dam but higher than the predicted value by 18%. Soydemir & Kjaernsli's equation only agree with compacted rockfill-membrane dam's, other equation's significantly differ from the predicted. (5) The prediction of sttlement by empirical equations cannot use to predict Dam settlmennt without strict classification of dam type so that the equations must be used after deeply consideration of dam type.
