Fig. 12 The Photo of Construction 7. SUMMARY AND KEYWORDS 1] It is not avoidable to have a large differential settlement between the high earth fill zone and rigid rcc or concrete zone, therefore we should avoid having this whenever possible. 2] Even though the leakage occurred but the dam shall be safe since it flows through the rcc material in which suffusion flow might not be able to occur and the leak occurred near the dam crest where hydraulic head is low. 3] Cracks in the rcc crest block due to the earthquake may not be harmful in the engineering point of view. However, for the community who lives downstream, unnecessary worries posted to them. Therefore, the rigid and brittle rcc crest block will be replaced with the more flexible grs wall. 4] After dam rehabilitation is completed, the mae suai dam reservoir will be full storage. 895
