“…Since the reflectance of water is nearly equal to zero in reflective infrared bands of remote sensing, the reflectance of the majority of land cover is greater than water. As demonstrated in previous studies (e.g., Chu et al, 2006;Cui and Li, 2011;Kuenzer et al, 2014), remote sensing images normally display a distinct water-land boundary, which can be determined on a GIS platform.…”

“…Wang et al (2006) in particular showed that there is a close correlation between sediment input and land-accretion in both the estuary and the delta of the Yellow River in the separate periods of 1953-1973(Shenxiangou and Diaokouhe courses) and 1976. While this proposition gained support from Bi et al (2014) in their analysis of the estuarine change of the YRD in the period -2011, Cui and Li (2011 identified that besides the close correlation with sediment input, land-accretion of the YRD in the period 1976-2005 also correlates closely with the quantity of water supplied from the river. In addition, these previous studies have focused on the delta's morphologic change only in specific short periods and/or on just parts of the delta, so it is necessary to examine if the correlations exist between land-accretion with sediment input and water supply over the delta for a long period.…”

“…Wang et al, 2006;Bi et al, 2014), whereas others determined both critical water and sediment conditions, yet quite separately (e.g. Cui and Li, 2011). In some cases different critical sediment and water conditions were given for different time periods, even in the same study (e.g.…”

“…Wang and Liang, 2000;Chu et al, 2006;Wang et al, 2006;Bi et al, 2014), but water supply is also important (e.g. Xu, 2002;Zhang and Hu, 2007a,b;Cui and Li, 2011). Sediment input provides material for delta construction while water supply provides the dynamic conditions for sediment transport and deposition.…”

“…Xu (2002) suggested that the effects of both water and sediment supply on the progradation of the YRD need to be determined in an integrated way; however, most studies so far have focused on these parameters separately (e.g. Wang et al, 2006Wang et al, , 2010Cui and Li, 2011;Bi et al, 2014). The lack of an integrated approach makes it difficult to evaluate the combined effects of water and sediment supply on delta progradation.…”

Progradation of the Yellow (Huanghe) River delta in response to the implementation of a basin-scale water regulation program

et al. 2015

The water and sediment supply to the lower reach and estuary of the Yellow (Huanghe) River have been altered to a very significant degree by the construction of numerous small to large reservoirs and the progressive implementation of water and soil conservation measures across the entire drainage basin since the late 1950s, followed by a basin-scale water regulation program since 2002. There is an urgent need to know how progradation of the Yellow River delta (YRD), an area on which people live and farm, has continued and will continue to respond to these controls. This study examines the changing patterns of water and sediment supply to the YRD over the period of 1950-2013 and, using remote sensing, it evaluates the morphological changes of the delta during 1976-2013. Although both water and sediment input to the delta have been described as declining significantly since the mid 1960s, we show that since 2005 the supply of water has remained at around 20 billion m 3 yr −1 and that for sediment at about 0.13 billion t yr −1 ; water input has been even slightly increasing. The dynamics of extension/shrinking and avulsion in river-mouth channels and accretion/erosion of shorelines is an integrated response to the complex variations in both sediment and water supply. This study develops a quantitative relationship between water and sediment supply and the area of land accretion and it predicts the critical condition for land accretion in the YRD. To ensure that delta land will not be lost, care is needed in the future implementation of the basin-scale water regulation program.

Delta channels are important landforms at the interface of sediment transfer from terrestrial to oceanic realms and affect large, and often vulnerable, human populations.Understanding these dynamics is pressing because delta processes are sensitive to climate change and human activity via adjustments in, for example, mean sea level, and water and sediment regime. Data collected over a 40-year period along a 110km distributary channel of the Yellow River Delta offers an ideal opportunity to investigate morphological responses to changing water and sediment regimes and intensive human activity. Complementary data from the delta front provide an opportunity to explore the interaction between delta channel geomorphology and delta-front erosionaccretion patterns. Cross-section dimensions and shape, longitudinal gradation and a sediment budget are used to quantify spatial and temporal morphological change along the Qingshuigou channel. Distinctive periods of channel change are identified, and analysis provides a detailed understanding of the temporal and spatial adjustments of the channel to specific human interventions, including two artificial channel diversions and changes in water and sediment supply driven by river management, and downstream delta-front development.

Channel geomorphology widened and deepened during periods when management increased water yield and decreased sediment supply, and narrowed and shallowed during periods when management reduced water yield and the sediment load. Changes along the channel are driven by both upstream and downstream forcing. Finally, there is some evidence that changing delta-front erosion-accretion patterns played an important role to the geomorphic evolution of the deltaic channel; an area that requires further investigation.

This study evaluates the historical coastal change and development along the eastern coastline of the Upper Gulf of Thailand between 1953 and 2019 based on a series of aerial photographs and satellite images. Long-term ($70 years) and short-term ($10 years) shoreline movement rates were analysed using the Digital Shoreline Analysis System (DSAS). Results of this analysis indicate that the shoreline along the western coast (WBK) of the Bang Pakong River mouth has undergone severe coastal degradation, with a land loss of about 980 ha over the last seven decades. Meanwhile, the eastern coastline (EBK) has developed continuously over this time span, resulting in a land growth of about 552 ha. Based on historical shorelines recorded since 1954, the shoreline recession along the WBK coast accelerated over five decades. The average shoreline change rate reached approximately À9 m/year in 2002 and is shown to be related to land subsidence, which was due to groundwater
