Importance: Cracks and ruptures at face slabs had appeared in several high CFRDs in the two decades before 2007.Some were with high leakages (> 1,000 liter/s) such as in Barra Grande (185m, Brazil) and Campos Novos (202 m, Brazil) both in 2005 , Mohale (145m, Lesotho) in 2006, Tianshengqiao 1 (178m, China) during reservoir impounding in 2003 and 2005, that means after 3 and 5 years of operation and Aguamilpa (187m, Mexico) and so on.
