Abstract

This study selected the Yinchuan Plain reach of the Yellow River with a length of 196 km as a case study, and searched each point of intersection of 153 cross-sections (interval between two adjacent cross-sections was 1.3 km) and river banks in 1975, 1990, 2010 and 2011, which were plotted according to remote sensing images in those years. Then the shift rates for the points of intersection during 1975–1990, 1990–2010 and 2010–2011 were calculated, as well as the average shift rates for different sections and different periods. The channel bank shift rates show evident spatial variation trends. It is highlighted that the temporal variation of the shift rate is influenced by human activities, while the spatial variation is controlled by the local difference in bank materials
