“…Extensive research has been carried out to understand different aspects of river science and open channel flow through field studies (Lamarre and Roy, 2008), physical models (Kasprak et al, 2015), numerical models (Hardy et al, 2003), and flume studies (Nelson and Morgan, 2018). However, the role of a confluence in integrated river management has only been identified recently, especially regarding the reciprocal adjustment of flow, sediment, and resulting morphological changes (Best, 1986;Biron et al, 1993;Creelle, Schindfessel, and De Mulder, 2017;Dordevic and Stojnic, 2016;Gaudet and Roy, 1995;Guillén Lude ña et al, 2017;Schindfessel, Creelle, and De Mulder, 2015;Tancock, 2014). Best (1986) noted that morphological features of different intersection geometries are not similar.…”
