Abstract: The purpose of this study consists in presenting a newly suggested river classification system based on the geomorphological criteria and applying it to some rivers in Korea. The suggested system uses the channel reach as a basic classifying unit, which is delineated by upstream and downstream tributaries. It adopts three major basic geomorphological criteria for classification: valley-floor width index, sinuosity and bed material size. The system is composed of 24 stream types. Concerning every stream type, valley forms, dominant bedforms and fluvial processes with disturbance elements are briefly presented. The Chungmi-chun and the Imjin River are classified by the suggested system for the evaluation of applicability.
