Abstract: Aerial photographs taken during floods are analyzed by the correlation method, which is one of the image processing techniques. In this method, cross-correlation coefficients of gray level intensities of the photographs are used to obtain two-dim ensional velocity distributions. The results show a good agreement with those obtained by a precision analytical plotter which is considered to be the most accurate instrument for analyzing aerial photographs. A large scale structure of the flood flow between high and low water channels can be observed in the Yodo River, Japan.
