This study aimed to determine the timeline and causes of sedimentation observed in a concrete-lined segment of a tributary of the San Francisco Bay, Corte Madera Creek (California, U.S.). The study evaluated two hypothetical scenarios: 1) complete flushing during high flows and subsequent re-deposition, and 2) gradual channel infilling. Using stratigraphic analyses, sediment elevation profiles, and a hydrodynamic model, the channel was determined to be infilling gradually rather than completely flushing and refilling.
