Abstract: Based on theoretical analysis and case studies, the paper points out that the influencing factors of flood routing and the attenuation of flood peak discharge include external factors like both river channel boundary etc. and internal factors. It emphasizes on the internal factors of one flood in addition to external factors. Regarding floods which could be regulated, the operation of reservoirs should be enhanced to form suitable floods based on different goals of experiments.

Keywords: attenuation of flood peak discharge, flood routing, flood-forming, optimum operation
