Concrete-Face Rock-Fill Dams (CFRDs) are rock-fill dams with watertight-concrete slabs on its upstream slope instead of its cen tral earth cores. The design for CFRDs are still largely empirical and typically based on past experiences. This paper presents a de scription of the concrete face slabs and leakage behaviors of two post-constructed CFRDs based on the data gathered through instrumentati on during the initial impoundment. The results show that the strain on the concrete face slab and the horizontal displacements of the vertical slab joints are slightly affected by both the seasonal temperature change and water loading during the initial impound ment. The deformation of perimetric joints are less affected by the temperature change, however it is significantly affected by the water loading during the initial impoundment. The leakage rate is significantly affected by the hydrostatic load and the deformation of the p erimetric joints.Key words : CFRD, Rockfill, Dam, Concrete face slab, Leakage                 .
