GEOMETRICAL MODELS FOR OPTIMUM SHAPE OF CONCRETE ARCH DAMS [PDF]
مجله مدل سازی در مهندسی, 2010 Concrete arch dams required less volume of concrete, when they are designed by an optimized geometrical model. These types of structures have better resistance against earthquakes because they are light, and can be built with lower prices.
