Abstract Based on 345 satellite images from 1991 to 2018, we examine the height, area and morphological changes of two large newborn river-mouth bars in the vulnerable Changjiang Delta as well as their influencing factors. The growth of inaccessible river-mouth bars is less affected by human estuarine activities, therefore, studying their growth shows particular promise in revealing the effects of relative sea level rise and human activities upstream of the river basin. We find the morphologic… Expand

Abstract This paper reviews the morphological change in the Yangtze River delta due to increasing human impacts from three major aspects. The first is the reduction of sediment supply to the oceanExpand
Detection of the Three Gorges Dam influence on the Changjiang (Yangtze River) submerged delta
TLDR
It is indicated that the Changjiang submerged delta went through high accumulation (1958-1978), slight accumulation (1978-1997), slight erosion (1997-2002); and high accumulation(2002-2009), despite the 70% reduction of the sediment load from upstream since the operation of the TGD in 2003, which suggests on a longer term, the distal sediment source from the upstream had little effect on the CSD.

Modeling the growth limit of the Changjiang Delta
River deltas grow in response to sediment discharge from the land. It is not clear, however, whether or not there is a limit for such growth. Conceptual geometric models are used in this paper, inExpand
