With the development of societies and economies, the process of industrialization and urban modernization is accelerating, urban populations are increasing, and more and more wastewater is generated and released. Large quantities of hazardous industrial and agricultural wastewater and domestic sewage are discharged directly into reservoirs, lakes, rivers and the sea, without adequate treatment. The wide range of pollutants discharged can degrade, interact, and transform in aquatic environments. When light, temperature, nutrients and other natural conditions are suitable, it is common for algal species to burst into bloom, causing serious damage to the ecological environment of the receiving water body. As the flux of river discharge into the sea increases year by year, the deterioration of coastal water environments accelerates. Meanwhile, variations in climate and vegetation impact basin hydrological proceses and river runoff into the sea.
Healthy aquatic environments are a necessary condition and key factor for human existence and sustainable development of social economies. In recent years, under the double pressure of severe water shortage and water pollution, it has become extremely crucial to prevent and control water pollution and protect and improve the water quality and ecosystem health of rivers and other receiving aquatic environments. Studying the influence of climate change on water environments, pollutant transport processes and mechanisms under different hydrodynamic conditions is an important theme in the fields of hydraulics and aquatic science, providing a scientific and theoretical basis for the protection of freshwater resources and marine environments.
The purpose of the current Research Topic is to invite and collate promising recent and new research trends in the fields of watershed hydrology, pollution transport, diffusion and transformation processes, surface and groundwater quality, and environmental water quality sciences. Areas covered by this Research Topic may include, but are not limited to:
- Hydrological effects of the watershed ecosystem on pollutant transport under varying environmental conditions.
- Responses of river pollutant diffusion to land use patterns, vegetation, and climate change.
- Hydrodynamic characteristics of estuarine and in nearshore environments
- Characteristics of pollutant migration in estuarine wetland systems.
- Transport and diffusion of pollutants in coastal waters.
- Pollutant transformation mechanisms and ecological effects.
- Response mechanism of watershed hydrological process to climate and vegetation variation.
- Hydrological response of watershed to land use/cover change.
- River sediment transport and riverbed evolution.
- High-resolution precipitation data fusion and multi-scale hydrological prediction method for watershed.
- Coupling relationship of vegetation-soil water – under groundwater - river runoff.
- Mechanism of water cycle evolution under the influence of human activities and climate change.
