To study the evolution of hydrochemical characteristics and the quality of irrigation water from a suburban river, a total of 54 water samples were collected from Xinbian River in Suzhou City (Anhui Province, China) from December 2019 to May 2020. Piper diagrams, Gibbs diagrams, and multivariate statistical analysis were used to analyze the hydrochemical characteristics and main ion sources. Research results showed that the content of main ions increased continuously from December 2019 to May 2020, among which SO42- and F- exceeded China’s surface water quality standards in April and May.

As an important part of the river ecosystem, vegetation has a significant influence on hydrodynamic characteristics, water quality, river morphology, and ecological habitat. Combining vegetation survey with the verified numerical model, this study aims to analyze the impact of floodplain vegetation patches on hydrodynamic characteristics in the old course of Fuhe River under various combinations of incoming flow discharges, and flood diversion discharges, and changes in the land use type. The equivalent Manning coefficient was adopted to quantify the additional resistance induced by plants in

Land use/land cover (LULC) change and water poverty scenario over time. In the present study, the samples were chosen from seven sampled villages for the Water Poverty Index (WPI) in the upper Tons River Basin. Among them, Ghunwara and Maihar Village exhibit the highest and lowest WPI, i.e., 98.1 and 62.91 out of 100, respectively. This indicates that villages with a high WPI face challenges in their water requirements, regardless of

Studies have emphasized that the presence of heavy metals in freshwater fish represents a global public health issue. Nigeria, being a developing nation with less emphasis on the quality of seafood consumed by the residents, ranks this study very vital. The policy implication of this study is the advancement of a healthy population in contemporary Nigeria. Hence, this study assessed heavy metal concentration in two fish species, Clarias gariepinus (Catfish) and Oreochromis niloticus (Nile Tilapia), in the Anambra River.

The water, food, and energy demands are the basic requirements of society. These demands are increasing daily due to an increase in population or lifestyle changes. To fulfill these ever-increasing demands, several water resource projects have come up which require the storage or diversion of river water. These interventions have caused widespread degradation of aquatic ecosystems. Due to the degradation of the aquatic ecosystem, several programs all around the globe began.

AbstractThe Wash drainage basin contains four principal river systems. Samples were collected from the freshwater and estuarine reaches of each of these, and silt- and clay-grade fractions were separated and examined by XRD. The clay mineralogy of each of the rivers is different; in the north the Witham sediments contain chlorite, the Welland and Nene samples contain vermiculite, with a higher proportion of kaolinite in the former, while in the south the Ouse sediments contain smectite. The clay fractions of the samples from the estuarine reaches all contain chlorite, confirming that non-fluvi

This paper describes the development of a prehistoric landscape by the river Nene at Grendon Lakes, partly revealed in the 1970s and partly during excavations in 1998 and 2001, which are reported in full. Two major phases of archaeological activity are evident, one interpreted as Neolithic–Early Bronze Age, the other as Iron Age. The gap between these is bridged by an environmental sequence reconstructed with the aid of a pollen core from an adjacent palaeochannel, which shows that human activity continued in the intervening period. The landscape is comparable in form, though not in scale, wit

Recycled water from factories has a positive impact on the categories assessed.
