Abstract: The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed. In addition, environmental design of channels can be integrated into channel design without compromising hydraulic efficiency. Difficulties in quantifying the effects of environmental features on hydraulic efficiency may be significant. However, solution of these problems should be considered as a challenge to stream ecologists, hydraulic engineers, and workers in related disciplines. This paper discusses new design criteria, selective clearing and snagging, woody vegetation and bank stabilization, complex cross sections, and institutional problems.
