One-decade-long observations of post-cut-off channel development and oxbow lake formation are presented to offer insight into the morphological response of the Morava River to neck cutoff. The main objectives were: calculation of the amount of sediment released to the channel by collapse of the meander neck, comparison of floodplain erosion and deposition rates before and after cut-off, and description of the rate and pattern of oxbow lake sedimentation. The amount of sediment released due to cut-off (35 000 m3) equalled 2 - 5 years of sediment input by lateral erosion averaged for the past six decades. Bank erosion rates substantially exceeded long-term averages (0.63 - 6.21 m year -1, post cut-off). Despite a low entrance angle, alluvial plugs in a newly formed oxbow lake were established within a few months. Between 2006 and 2016, sedimentation of the alluvial plugs proceeded at an average rate of 0.55 m year -1, reflecting the time since cut-off and the frequency of overbank flows.
