Abstract

In this study, both laboratory and field investigations were conducted to evaluate patterns of flow and erosion/deposition at the downstream exit of an abandoned meander bend. First, the paper outlines the experimental methods used to obtain measurements in the laboratory (physical model of the Morava River, Slovakia) and in the field (Port-Galland cutoff meander, Ain River, France). Both cases yielded consistent and complementary results from which a generic scheme for flow patterns and morphological evolution was derived. A simple analogy with flows in rectangular side cavities is proposed. Finally, a discussion is presented on the consistency of the hydro-sedimentary observations and on the effects of complex flow processes (three-dimensional, intermittent) on sediment transport in such cases
