Abstract Hurricanes can benefit wetland accretion by augmenting the delivery of mineral sediment, an essential process allowing marshes to offset submergence during rising sea levels. Using Hurricane Gustav (2008, Louisiana) as a control, we examined eight synthetic storms with varying characteristics (track, speed, intensity, size) evaluate sediment exchange between inner shelf and bay bay‐to‐marsh interfaces. All showed net landward from marsh—storms closer proximity, higher slower forward speed positively correlated exchange; storm size had little impact. Except for slow‐moving (½ Gustav), our analyses suggest that most hurricane scenarios cause erosion, because more is conveyed wetlands than replenished erosion shelf. Our results ongoing deepening will likely worsen

Hurricanes benefit wetland accretion by augmenting the delivery of mineral sediment, an essential process allowing marshes to offset submergence due rising sea levels. Using Hurricane Gustav as a control, we examined eight synthetic storms with varying characteristics (track, speed, intensity, size) evaluate sediment exchange between inner shelf and bay bay-to-marsh interfaces. All showed net landward transport from marsh—storms closer proximity, higher slower forward speed positively correlated exchange; storm size had little impact. Except for very slow-moving storms, most scenarios cause erosion more is conveyed wetlands than replenished shelf. This deficit suggests future deepening bay, which will worsen accelerating sea-level rise.
