Researchers created a model that uses the movement at fault lines to understand river flow and vice versa. In California's Carrizo Plain, many stream channels are offset by movement along the San Andreas Fault. A new interpretive framework helps explain how stream channels and fault movement interact to shape the topography of the landscape.
