ABSTRACT=Highlights 1. Taking the impoundment operation of Shuikou Reservoir in 1993 as the node, the long-term siltation state of the subaqueous delta in the Minjiang Estuary changed to erosion, and the critical value of the transition is about 570.3 × 10 4 t / yr. 2. The change of sediment load into the sea is the main driving factor for the adjustment of estuarine geomorphic evolution in the past 70 years. 3. The sudden significant siltation in 1998-2005 may be caused by frequent typhoons and frequent floods in the Minjiang Estuary during this period.
