WebA single discharge, known as the channel-form-ing discharge, is often used as the representative value for channel stability assessment and design. Although both Q e and the bankfull discharge Q b are widely considered estimates of the channel-forming discharge, Quader et al. (2008) cite nu-merous sources that recommend use of Q e …

WebThe ‘‘channel-forming’’ or ‘‘dominant’’ discharge Qcf is often used as the representative value for stability assessment or chan-nel design. The channel-forming discharge concept is that, for a given alluvial channel geometry, there exists a single discharge that given enough time would produce width, depth, and slope Webrepresenting the channel-forming discharge in a stream (Copeland et al., 2000). It is defined as the highest flow a channel can convey before it starts to spill onto its floodplain (Leopold et al., 1964) and can be identified in the field using physical indicators (Mulvihill and Baldigo, 2012).
