River research focuses on understanding the physical, chemical, and biological processes that occur in rivers, as well as the interactions between rivers and their surrounding environments. This includes studying the flow dynamics, sediment transport, water quality, biodiversity, and ecosystem services provided by rivers. Researchers in this area often investigate the impact of human activities on river systems, such as pollution, habitat destruction, and water management practices. Ultimately, the goal of river research is to inform conservation and management efforts to protect and restore river ecosystems.
