Abstract：
There are three different channel patterns in the lower Yellow River, including the wandering pattern, the transitional pattern and the confined meandering pattern. On the above three types of river channels, four sections of Jiahetan, Gaocun, Luokou and Lijin were selected for research. According to the geomorphological characteristics, the sections were divided into 11 geomorphological units. They are the left levee to the left production embankment, the left high floodplain from the production embankment to the top of the left high bank, the left high bank slope, the left low floodplain from the foot of the left high bank slope to the top of the left low bank, the left low bank slope, the main channel bed, the right low bank slope, the right low floodplain from the foot of the right high bank slope to the top of the right low bank, the right high bank slope, the right high floodplain from the top of the right high bank to production embankment, and the right high floodplain from the right production embankment to right levee. Based on the cross-sectional scale, we studied the erosion/deposition variation patterns and influencing factors of channel bed, bank slopes and floodplains of different river patterns, and obtained the erosion/deposition changes dataset on lower Yellow River cross-sectional geomorphological units (1966-2014). The dataset is consisted of: (1) geo-location data of the four sections; (2) flood season, non-flood season and annual erosion/deposition area of each geomorphic unit of the four sections; and (3) flood season, non-flood season, annual mean water and sediment discharge of the four sections. The dataset is archived in .shp and .xlsx formats, it consists of 9 data files with data size of 92.1 KB (Compressed into one single file with 84.4 KB). The analysis paper was published on the Water, Vol. 11, No. 2, 2019.
