“…After the Xiaolangdi Reservoir fully operated, the delta accretion rate significantly reduced at both the interannual and decadal scales, due to the dam-induced drastic decline of sediment delivery (Zhou et al, 2015;Jiang et al, 2017;Wu et al, 2017;Fu et al, 2021). The deltaic channel also experienced incision and deepening processes under changing water and sediment supply (Zheng et al, 2018;Han et al, 2020). Groundwater extraction and oil exploitation at the YRD accelerated the land subsidence and shoreline retreat (Higgins et al, 2013;Kuenzer et al, 2014).…”
