The spatial and temporal variation of total suspended solid concentration in Pearl River Estuary during 1987–2015 based on remote sensing

Assessing the Effects of the Hong Kong‐Zhuhai‐Macau Bridge on the Total Suspended Solids in the Pearl River Estuary Based on Landsat Time Series

“…It was estimated that about 75.29 Mt of sediment was transported to the South China Sea between 1955 and 2005 through the PRE (Dai et al, 2007). As observed in previous studies, TSS in the PRE covers a large range from <1 to 140 mg L −1 (Liu et al, 2009; Wang et al, 2018; Zhao et al, 2018). It has noticeable spatial patterns that are characterized by high values close to the mouth of outlets and low values on the seaward side.…”

“…With respect to the turbid Pearl River estuary, a number of remote sensing related studies for TSS focused on algorithm development and assessment (Dai et al, 2008; Fang et al, 2010; Wu et al, 2013; Xing et al, 2013; Ye et al, 2014; Zhao et al, 2018). Only a few studies concentrated on long time series of TSS based on remote sensing data (Wang et al, 2018; Zhan et al, 2019). In recent years, many constructions have been built in the Pearl River estuary (PRE).…”

Remote Sensing Evaluation of Total Suspended Solids Dynamic with Markov Model: A Case Study of Inland Reservoir across Administrative Boundary in South China

“…With a total storage capacity of 1.151 billion m 3 and a catchment area of 1440 km 2 , Hedi Reservoir is a key source of water supply security in western Guangdong and one of the five major drinking water sources in Guangdong Province [36]. The spatial and temporal distribution of TSS in the reservoir is not only closely related to local human activities such as navigational transportation, aquiculture and even illegal-profit business processes [32,37], but also becomes the focus of attention for sustainable development in human society especially in the planning of ecological preservation areas and urban construction [17]. In recent years, the rapid economic development and the increasing human activities have caused some river sections to be polluted to varying degrees, and the water use in the basin has become increasingly tense.…”

“…Therefore, it is particularly important for real-time monitoring and management of the aquatic environment in the reservoir area to reveal the dynamic of TSS. Since the release of the guidance for the river chief system by the General Office of the State Council of China in 2016, the research of TSS in inland water including lakes and reservoirs has been paid more lasting attention, and the associated research has been conducted by a variety of scholars, governments and social communities [6][7][8], such as the Río Tercero reservoir (Córdoba, Argentina) [6], the Mekong and Bassac Rivers [9,10], the Amazon River [11], Taihu Lake [8,12], the Yangtze River [13][14][15] and the Pearl River [16][17][18][19].…”
