ABSTRACT
One billion people will be added to the world’s population in the next 10 years, while today, many of under developed countries have some problems of lack of water. It is important to have a fast and less expensive method of dam construction. The first RCC dam was put into operation in Japan in 1981, and since then till 2004, about 475 dams of this kind have been constructed in 32 countries (Dunstan 1999).
