“…In Figures 3 and 6, the δ 18 O and δ 2 H values in the low-flow season were lower than that in the high-flow season in the North and West River, which were opposite to the South River, the Mulanxi River, and the Minjiang River [46,47]. This was probably because the Mulanxi river water was mainly recharged by groundwater and the Minjiang river water experienced more evaporation in the dry season, however, the factors impacting the isotope composition were different in the North and West River due to the large rainfall amount and low evaporation according to our explanation in Section 4.1.…”

“…Instead, the water isotopes in the mid-lower reaches were generally lighter downstream because of the increasing mixing proportion with rain water. However, in the low-flow season, it was more complex in the West River, which was explicable by the different water source, water storage, and evaporation [46]. and anthropogenic processes.…”

The stable isotope technique of oxygen and hydrogen (δ18O and δ2H) and deuterium excess (d-excess) was used to investigate distribution characteristics in June 2017 and January 2018 in the Jiulong River, southeast China. The results revealed that (1) seasonal isotopic composition was mainly controlled by precipitation. It enriched lighter water isotopes in winter more than in summer because of the aggravating effect of low temperature and great rainfall. (2) Spatial distribution of the North, West, and South River showed increasing enrichment of heavy isotopes in that order. In the high-flow season, the continuous high-flow made δ18O and δ2H homogeneous, despite increasing weak evaporation along water-flow paths in the West and South River. In the low-flow season, there was a decreasing trend in the middle and lower reaches of the North and West main stream and an increasing trend in the South River. (3) O and H isotopic geochemistry exhibited natural and anthropogenic influence in hydrological process, such as heavy rainfall and cascade reservoirs. The results showed that O and H isotopes are indeed useful tracers of the water cycle.

“…The present study was undertaken along the Minjiang River which serves as the main water source for agriculture, industry, and domestic purposes in the Fujian Province. , Its basin has many hydropower, forest, animal, and plant resources . Approximately, 70%–80% of the annual freshwater discharge is concentrated from April to September under the influence of the monsoon climate . An increase in human activities in and around the river basin has resulted in contamination and deterioration of the river resources .…”

This study involves elucidation of spatial and temporal influences on horizontal and vertical distribution and fate of contaminants of emerging concerns (CECs) in riverain systems. In total, 23 CECs encompassing antibiotics, nonantibiotic drugs, and bisphenol analogues were detected. The antibiotic concentrations were relatively higher in deep water than in surface water. Spatial connectivity and spatial autocorrelation suggested the occurrence and concentration of the majority of the CECs devoid of neighboring site influences, owing to shorter correlation lengths than the average distances between the sampling sites, hence indicating the localized distribution of CECs in surface water. The PCA biplot indicated that bisphenol A and methyl paraben were mainly responsible for the seasonal variations. Both negative and positive correlations existed between CECs and the environmental parameters to cause temporal variations in CEC contaminants. Spatial structure analysis by singular vector decomposition (SVD) analysis was used to measure the sitewise contribution of CECs. The results indicated relatively higher CEC contaminants and deteriorated water quality in the downstream sites rather than in the upstream sites. This study effectively demonstrated the use of different chemometric techniques for in-depth understanding of various spatial and temporal influences on the fate and horizontal and depth distribution of CECs in riverain systems.

“…In addition, the water yield of coastal aquifer is good, resulting in the large amount of groundwater input (Xuet al , 2014;Xia et al , 2016;Guo et al , 2017;. In the east coast of Hainan Island, groundwater input pose a huge impact on the local environment (Wang and Du, 2016), while the input of groundwater in the Minjiang River estuary is very limited (Liu et al , 2016). However, due to the difficulties in field investigation or research, the requiry of the cooperation of scholars in ocean dynamics, groundwater dynamics, ocean and groundwater geochemistry, isotopic chemistry, etc.…”

In recent years, hydrogeologists have paid more and more attention to the discharge of submarine groundwater(SGD), which is a typical and important process of the interaction between seawater and groundwater in coastal areas, tidal flats and estuaries.As an important sources of water and chemical materials to ocean, SGD affects the global water cycle and coastal ecological environment. SGD also influence the transport path of pollutants from land to the sea. Therefore, it affects the local and global circulation of coastal groundwater and seawater. Since it usually occurs in aquifer, it is easily overlooked by the researchers. In addition, due to the uncertainty of SGD in time and space, it is difficult to be measured accurately. Aiming at recently study, this paper will discuss the research process, research method, research field and environmental significance of SGD on the coast of the Huanghai and the Bohai. Based on the analysis of the existing research results, some suggestions on improving SGD investigation are put forward.
