Identifying the pattern of delta morphological change under decreasing sediment flux due to dam construction is essential for sustainable management in such densely populated coastal areas. In this study, we investigated processes Yangtze mouth bar and prodelta based on bathymetric data a decadal-interannual scale (1958, 1978, 1997, 2002, 2007, 2010, 2013 2015). We found that strong accretion (...
