Water systems research focuses on the study and understanding of the complex network of interconnected structures and processes that comprise the Earth's water cycle. This includes the movement, distribution, and management of water resources, as well as the impact of human activities and climate change on water quality and availability. Researchers in this field may investigate topics such as water conservation, water treatment technologies, watershed management, water policy and governance, and sustainable water resource development. The goal of water systems research is to ensure the sustainability and resilience of our water supply for both humans and the environment.
