Although many studies regarding bank erosion and accretion can be found in the literature, it is not common to find works studying the interaction between opposite banks. Some existing morphodynamic models describe bank erosion as an event that depends on near-bank flow and bed topography, as well as on eroding bank properties. Most developed models do not include opposite bank accretion, with the exception of, e.g. Asahi et al. (2013) and Eke et al. (2014). . These models can represent opposite bank dynamics. Analyses of bank-to-bank interactions, showing for instance where the effects of depositing bank push are felt (where exactly opposite bank erosion occurs), are lacking. Observations by Nanson and Hickin (1983) on the Beatton River, in Canada, suggest that bank accretion is important for opposite bank erosion to occur, in addition to the magnitude and duration of hydrological events. The present study focuses on the interaction between opposite river banks. The aim is to describe how bank accretion influences opposite bank erosion and whether there is a spatial lag in this interaction. This paper presents only some preliminary results.
