The major aims of this book, "Watershed Water Environment and Hydrology under the Influence of Anthropogenic and Natural Processes", are to focus on innovative/new ideas on the watershed water environment from different perspectives across the field
distinguish the evolution of watershed water ecological and environmental quality
clarify the biogeochemical cycling of elements or pollutants
identify and quantify the sources of pollutants
and assess the ecological risk and human health risk of pollutants in the water environment at different watershed scales. In particular, eight peer-reviewed articles were collected, mainly reporting the hydrochemistry-based watershed weathering processes and their environmental implications, trace elements and their risks, and the nutrients cycle in river-reservoir systems. Overall, these papers contribute to several aspects of the watershed water environment and are valuable for river water resource protection and management.
