It is an important safety feature that helps to prevent overtopping of the dam during floods.<\/p>\n<p>The height of the wave is a major factor in determining the required freeboard. The higher the wave, the greater the risk of overtopping. Therefore, the freeboard is typically set to be at least 1.25 times the height of the wave.<\/p>\n<p>This value is based on engineering standards and experience.
