Steel sheet pile revetments have been widely used in agricultural canals in the low flatland areas with drainage fields. Many facilities are more than 40 years old after installation. The progression of corrosion is examined by means of visual and thickness surveys. In this study, we attempted to estimate the degree of corrosion using visible images.
