Hence, the bed discordance inhibits the formation of a zone of horizontal flow recirculation allowing the main-channel flow to move unimpeded downstream. This paper presents the results of an experimental study on the bed topography evolution in a discordant bed channel confluence where sediments were supplied in both channels. 2.
