Abstract

This paper intends to make channel-fill sedimentological sequences more useful recorders of channel abandonment processes and palaeofloods, for which improved understanding is needed of the internal build-up of channel fills. The AA. review oxbow lake infilling along meandering rivers, and supplement this with highly detailed descriptions of 2 selected field examples of channel fills from the apex-region of the Netherlands' Rhine delta. From these examples it becomes clear that regional setting and type of abandonment result in different channel-fill end-members; oxbow cutoffs generally produce thick laminated clayey fills as the channel entrance is plugged rapidly, avulsion-abandoned channels are filled with coarse (proximal) deposits as a result of a maintained open river connection. A sedimentary-architecture descriptive scheme that distinguishes elements from these 2 stages of channel-fill development is proposed
