Abstract
A stable channel is one in which channel dimensions of slope, width, and depth remain balanced with equilibrium condition between input and output sediment discharge and erosion and sedimentation of channel beds and banks. In the analytical method of stable channel design, stable channel slopes and depths with given channel widths are determined by satisfying the condition that the upstream incoming sediment rate is equal to the sediment transport rate at the design channel. Therefore, the most sensitive parameter when designing a stable channel is the choice of a sediment transport equation applied for the channel design. The Stable Channel Analysis and Design (SCAD) program has been developed for the better option of various sediment transport equations and for calculation of a unique solution considering design constraints such as fixed width and depth as well as various solutions for stable channel condition with a wide range. The study reach of Naesung Stream in Korea has been selected for this study. The Naesung Stream is a tributary of Nakdong River and mostly sand bed. The stable channel analysis and design for the study section has been performed using the SCAD program with different sediment transport equations for sensitivity analysis and design constraints.
