Morphodynamics of the rock-bound outlets of the Pearl River estuary, South China — A preliminary study

Delta changes in the Pearl River estuary and its response to human activities (1954–2008)

“…1b). Sediment load from the rivers plays an important role during the delta forming process (Li et al, 2001;Wu et al, 2010). Eventually water discharge and sediment load enter a complex network of distributaries, with a channel density of 0.68 km/km 2 e1.07 km/km 2 , and flow out through the eight "gates", Humen, Jiaomen, Hongqili, Hengmen, Modaomen, Jitimen, and Hutiaomen, into estuarine bays (Chen and Chen, 2002) (Fig.…”

Recent geomorphic change in LingDing Bay, China, in response to economic and urban growth on the Pearl River Delta, Southern China

“…In recent years there have been a number of published studies on changes in the water and sediment flux from the Pearl River drainage basin as well as the estuary's sedimentary environment (e.g., Jia and Peng, 2003;Jia et al, 2005;Luo et al, 2007;Zhang et al, 2008). Much of the recent literature, however, has emphasized sedimentation and pollution within the estuary (Lin et al, 1998;Cao et al, 2004;Liu et al, 2005;Owen, 2005;Ma et al, 2002;Fu et al, 2003;Xing et al, 2005;Dai et al, 2008;Zhang et al, 2009;Liu et al, 2010;Wu et al, 2010). The relatively few papers dealing with changes in the coastline and bathymetry in the Pearl River (Lin et al, 1995;Seto et al, 2002;Chen et al, 2005: Chen et al, 2006Zhang et al, 2008;Zong et al, 2009 Wang et al, 2013) have dealt primarily with post-1980 changes.…”

Long-term process-based morphodynamic modeling of the Pearl River Delta

“…We used 1689 core records to rebuild the water depth of the paleo-Pearl River receiving basin at 6000 year BP. Details on this method can be found in the literature (Wu et al 2010). Figure 4a presents the reconstructed topography of the paleo-Pearl River estuary.…”

“…As a result of this large sediment load and the occurrence of reclamation over the past several decades, the "Modaomen" passage has expanded toward the sea more rapidly than the other outlets. Hydrographical surveys denote the presence of a single estuarine jet system (Wu et al 2010). At one point during the evolutionary history of the PRD, the "Modaomen" passage was a large-scale bi-directional system (Fig.…”
