ynamics of flow, sediment and morphology of estuarine deltas worldwide have been profoundly altered by anthropogenic
interventions and climatewarming since the last century.TheYangzte estuarine delta (YED) is ideal to study such alterations
and recent studies there have mostly focused on the impact of Three Gorges Dam. Our new studies and observations show
that coastal engineering constructions and climate-induced sea level rise are transforming YED. For the past four decades, we
observed local tidal datum rise of 15–43 cm in which climate warming-induced sea level rise accounted for 8 cm. During the
same period, the tidal limit has migrated about 220 km upstream to Jiujiang, where it was located more than 2000 years ago
during the Jin Dynasty. Since 2013, a unique shift of bed morphology from a muddy flat bed to a dune bed made of coarse silt
also appeared in the channels of estuarine turbidity maximum. These results have global implications in formulating strategies
to combat the combined effects of climate change and other human interventions driven by coastal development needs.
