What is it about?
This work examines California’s water resources by modeling the entire water cycle as one connected system. The study combines surface water, groundwater, evapotranspiration, precipitation, and atmospheric processes to better understand how water moves through the California Basin and how groundwater use affects long-term water availability.

Why is it important?
California depends heavily on limited water resources for cities, agriculture, industry, and ecosystems. By modeling the complete water cycle as a single model, this work helps show how different parts of the water system affect one another. This can improve water planning, earth system modeling, drought response, and understanding of how groundwater pumping changes the broader water system.
Perspectives
Writing this paper brought together my deep passion for California’s water resources, my modeling skills, and my knowledge of the field. I began studying California water resources in 2009 as a master’s student at Stanford University. Later, in 2019, I walked across California on the John Muir Trail, where I was able to experience the Sierra Nevada’s water systems firsthand.
