This paper describes the dominant bed load transport circulatory pattern over the tidal channel confluence as well as the scour hole genesis and evolution in Bahía Blanca estuary, Argentina. In addition, the AA. detail the bed morphology associated with the sediment availability of each channel and sedimentary facies. As scour holes exhibit similar characteristics, their focus of attention was centred on a scour hole located inward, in the first bifurcation of Tres Brazas channel. The seismostratigraphic information collected in this study indicates that the depression was originally a fully erosive morphological feature. A descriptive model of the morphological evolution at a channel confluence is presented in this study
