Table 2indicates that the annual average water depth was greater than 32.49 cm, and the values gradually declined during monitoring period. The annual average flow rate exceeded 0.08 m/s; the maximum value was recorded in 2018 and the minimum value was recorded in 2020. This shows that the hydrodynamic conditions in the basin gradually deteriorated...
The relationship between different water parameters is represented by Pearson's correlation coefficient (r). The correlation is considered strong if the r value is greater than 0.7, whereas it is considered weak if the r value is lower than 0.3. A moderate correlation is considered to exist when r value lies between 0.3 and 0.7 (Emenike et al. 2018...
PCA is a multivariate statistical method that can be used to identify the correlation between variables (Xiao et al. 2019). The principal components (PCs) among the hydrochemical characteristics of the surface water samples were identified using a scree plot (Fig. 3) and PC loadings (Table 3) (Zhang et al. 2019). Factors with eigenvalues greater th...
The data obtained from the surface water samples collected from the Maozhou River trunk and branch streams were analyzed using one-way ANOVA (Tables 4 and 5). During the monitoring period, COD and LAS exhibited a statistically significant change trend (p < 0.01), whereas the other parameters did not. The surface water quality parameters exhibited s...
HCA was used to cluster water samples with similar hydrochemical characteristics into groups. A visual overview of the clustering process is presented as a dendrogram. Boreholes that exhibit similarities are primarily categorized into three distinguishable groups. According to the dendrogram, water samples were mainly categorized into eight groups ...
Based on the water quality, the eight groups of samples were classified according to the classes specified in the Environmental Quality Standards for Surface Water (China 2002). One group (G6) belonged to Class III, two groups (G7 and G8) belonged to Class IV, one group (G5) belonged to Class V, and four groups (G1, G2, G3, and G4) were classified ...
For a drainage basin located in an urban built-up area, especially one that has a large number of factories and residential areas along both banks of the river, it is particularly important to gain an understanding of the temporal and spatial variations in surface water quality to visualize the effects of human activities and tides on the water qua...

Jul 9, 2022 · The Maozhou River is the longest river running from southeast to northwest in southern China's Shenzhen City. It has shifted from the most polluted river in Guangdong Province to a typical role model in remarkable improvement of the water environment in China over the past six years. Maozhou River was seen as a 'scar' of Shenzhen.
Meizhou (Chinese: 梅州, Hakka Chinese: Mòichû) is a prefecture-level city in eastern Guangdong province, China. It has an area of 15,864.51 km 2 (6,125.32 sq mi), and a population of 3,873,239 as of the 2020 census.
