There is an increased demand for understanding the transport and fate of contaminants once they are released into waters in relation to the environmental and ecological effects for rivers, lakes, reservoirs, estuaries, and groundwaters. Contaminants dissolved or not dissolved into water will be transported and spread with the flow; sediment-contaminant interaction further introduces physical and chemical complexity into the transport process. Accurate analysis and prediction of the transport of the contaminant cloud, including the peak concentration and spatial distribution, are crucial for various applications, such as environmental risk assessment and water pollution control.
Furthermore, environmental and ecological hydrodynamics interact with biogeochemical processes in natural waters, affecting the transformation of contaminants and their ecological effects. For example, harmful algal blooms are associated with the widespread problem of water eutrophication. Natural streams and wetlands act as reactors and can reduce contaminant levels and purify the water. The application of water environment and ecology restoration also requires an awareness of the inherent hydrodynamic and biogeochemical mechanisms.
The aim of this Research Topic is to highlight new advances in our understanding of the hydrodynamics and biogeochemical processes of various contaminants in waters. It is meaningful to both the scientific community and governments with responsibilities for managing water environments and ecological integrity. We encourage submissions on analytical, numerical, and experimental studies involving the research frontiers of transport and fate of contaminants in waters. Original Research articles, Reviews, and Opinions on methods are welcome.
Important subject areas of this Research Topic include but are not limited to:
• Environmental and hydro-ecological research
• Sediment transport and fate of contaminants
• Wastewater treatment
• Constructed wetlands
• Biogeochemical processes of contaminants in aquatic environments
• Eutrophication and harmful algal blooms
• Environmental risk assessment
