Abstract
Dominant discharge may be defined as the steady discharge which could form or maintain the average geometric properties of a mobile-bed channel. For practical purposes, dominant discharge may be approximated by a representative discharge based on a hydrological definition or based on the stage corresponding to an identifiable geomorphic feature. An analysis of 71 relatively stable gravel-bed river reaches in Alberta, Canada, was utilized as the basis for adopting the 2-year flood (log-normal analysis) as the representative discharge when considering a hydrologically based definition. The discharge corresponding to the elevation of the valley flat was considered to be the representative discharge for channels which are not excessively entrenched when considering a geomorphologically based definition.
