Study on Ecological Scheduling of the Xiaolangdi Reservoir Based on the Ecological Needs of Estuarine Fishes

open access: yesMATEC Web of Conferences, 2018
The total water amount into the Yellow River estuary is significantly reduced with the construction of a series of reservoirs in the Yellow River, which has a lot of adversely effects on the fishes and fishery resources in the estuary.

Study on the influence of industrial structure optimization on water environment and economy: A case study of Changzhou city

open access: yesFrontiers in Earth Science, 2023
Economic development and large amounts of industrial production have led to environmental deterioration. The assessment and prediction of water environment capacity (WEC) are crucial supports for water quality target management.

Sediment transport and dispersal in the nearshore of “flash-flood” rivers [PDF]

open access: yes, 2014
River sediment dispersal on the near-shore of “flash-flood” rivers is investigated using a coupled wave-current-sediment transport model. Besòs and Llobregat rivers (short and mountainous rivers in NW Mediterranean Sea, near to Barcelona City) are used ...

Influence of salinity and water content on soil microorganisms

open access: yesInternational Soil and Water Conservation Research, 2015
Salinization is one of the most serious land degradation problems facing world. Salinity results in poor plant growth and low soil microbial activity due to osmotic stress and toxic ions.

Effects of typical artificial reefs on hydrodynamic characteristics and carbon sequestration potential in the offshore of Juehua Island, Bohai Sea

open access: yesFrontiers in Environmental Science, 2022
The ocean system provides abundant food resources and suitable habitats for numerous animal and plant species. However, the ecological health of the ocean system has deteriorated due to intensified human activities over the past decades.

Soil carbon and nitrogen erosion in forested catchments: Implications for erosion-induced terrestrial carbon sequestration [PDF]

open access: yes, 2015
Lateral movement of organic matter (OM) due to erosion is now considered an important flux term in terrestrial carbon (C) and nitrogen (N) budgets, yet most published studies on the role of erosion focus on agricultural or grassland ecosystems.

Cross-Medium Control of Water and Soil Environmental Pollution in Watershed

open access: yes中国工程科学, 2022
Pollutants have complex source-sink relationships in water and soil environments at a catchment scale, and the transformation of pollutants in water and soil environments is primarily controlled by various water-soil interface processes.

Formation of siliceous sediments in brandy after diatomite filtration [PDF]

open access: yes, 2015
Brandy is quite a stable spirit but sometimes light sediment appears. This sediment was separated and analysed by IR and SEM-EDX. It was revealed that the sediment is composed mostly of silica and residual organic matter.

Controls on Cyclic Formation of Quaternary Early Diagenetic Dolomite

open access: yesGeophysical Research Letters, 2018
The origin of sedimentary dolomite and the factors that control its formation within the geological record remain speculative. In most models, dolomite formation is linked to evaporative conditions, high water temperature, increasing Mg/Ca ratio ...
