Extreme precipitation from hurricanes and atmospheric rivers can lead to increased flooding in the world’s coastal zones, where more than 630 million people reside. Tidal marshes act as important buffers in these areas, absorbing the initial impact of storm surges and strong winds. In addition, tidal marsh ecosystems rely on storm events to deposit sediments that help with marsh accretion.
In a new study, Thorne et al. focused on tidal marsh accretion and elevation change in the San Francisco Bay after an atmospheric river event in 2016-2017.
