This paper uses a combination of remote sensing techniques (LiDAR, GPR, ER), borehole survey and chronometric dating to test differentiation in river style in the confluence-zone of a medium-sized, mixed-load, temperate river system (Trent, UK), which on the basis of planform evidence appears to conform to the meandering model. However, the analysis of "confluence sediment body stratigraphy" demonstrates that the confluence does not correspond with a simple meander migration model and chronostratigraphic data suggests it has undergone 2 major transformations. Firstly, from a high-energy braid-plain confluence in the Lateglacial, to a lower-energy braided confluence in the early to middle Holocene, which created a compound terrace. Second, incision into this terrace, creating a single-channel confluence with a high sinuosity south bank tributary (the River Soar). The late Holocene evolution of the confluence can be seen as a variant of the incisional-frequent channel reorganization (avulsion) model with sequential downstream migration of the reattachment point
