Both figures show cumulative grain size distribution. While converting the data to cumulative per cent, one set of data were duplicated into what should be blank cells in the spreadsheet. This resulted in horizontal sections in some of the cumulative curves that should not be there (e.g. Fig. 10, all ‘bank top sediment’ curves). This does not affect the results or conclusions of the paper.
