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.
