The number of floods per year for the investigated channel with a drainage area of 0.3 km 2 during the period from 1972 to 1983 varied from 7 to 44 (Fig. 2). The thickness of the moistened loam crust reached i0 mm, and the calculated depth of erosion of the channel during the i0 years was 0.67 m. Under prototype conditions, erosion of the channel varied within 0.40-1.10 m. In the calculations the coefficient m was assumed equal to i. By varying this coefficient, which takes into account the effect of various factors -intermittent work of the channel, presence of suspended colloidal and bottom-corroding sediments, vegetation, sinuosity, etc. -we can obtain complete agreement of thecalculated values and values measured on site.

“…Copeland's method, one of the analytical methods used for SAM of the US Army Corps of Engineers, is most widely used for evaluation and design of stable channels in alluvial rivers [6]. This method is similar to that of Abou-Seida and Saleh [11]. Among 3 unknown variables (channel width, slope, and depth of a stable channel), any two ones are calculated first.…”

As channel evaluation for abandoned channel restoration design, this study sought to exam channel changes from the past to the present and predict subsequently occurring river responses. For the methodology, channel geomorphology changes were evaluated through image analyses of annual aerial photographs to complement the limited river data. Channel responses were predicted using an analytical stable channel model, the SAM (Stable Channel Analytical Model) program, based on a stability theory as well as empirical equations for equilibrium channel. The results of the geomorphological channel changes showed that channels became narrower and bed levels became lower, whereas vegetated bars expanded. The channel response prediction results, narrower channels with deeper depths and mild slopes, were expected compared with the current condition. The channel response, obtained by the field measurement data, image information, and stability theory, are in relatively good agreements showing the reliability of the application suggested in this study. Consequently, the comprehensive channel evaluation approach is expected to be applicable to abandoned channel restoration designs from the aspects of channel geomorphology and hydraulics.
