A model ensemble for projecting multi‐decadal coastal cliff retreat during the 21st century A model ensemble for projecting multi‐decadal coastal cliff retreat during the 21st century
Sea cliff retreat rates are expected to accelerate with rising sea levels during the 21st century. Here we develop an approach for a multi‐model ensemble that efficiently projects time‐averaged sea cliff retreat over multi‐decadal time scales and large (>50 km) spatial scales. The ensemble consists of five simple 1‐D models adapted from the literature that relate sea cliff retreat to...

Projected 21st century coastal flooding in the Southern California Bight. Part 1: Development of the third generation CoSMoS model Projected 21st century coastal flooding in the Southern California Bight. Part 1: Development of the third generation CoSMoS model
Due to the effects of climate change over the course of the next century, the combination of rising sea levels, severe storms, and coastal change will threaten the sustainability of coastal communities, development, and ecosystems as we know them today. To clearly identify coastal vulnerabilities and develop appropriate adaptation strategies due to projected increased levels of coastal...

Estimating fluvial discharges coincident with 21st century coastal storms modeled with CoSMoS Estimating fluvial discharges coincident with 21st century coastal storms modeled with CoSMoS
On the open coast, flooding is largely driven by tides, storm surge, waves, and in areas near coastal inlets, the magnitude and co-occurrence of high fluvial discharges. Statistical methods are typically used to estimate the individual probability of coastal storm and fluvial discharge occurrences for use in sophisticated flood hazard models. A challenge arises when considering possible...

The influence of sea level rise on the regional interdependence of coastal infrastructure The influence of sea level rise on the regional interdependence of coastal infrastructure
Sea level rise (SLR) is placing both immediate and long‐term pressures on coastal communities to take protective actions. Projects in the United States, and in many locations throughout the world, generally involve local jurisdictions raising the elevation of shoreline protection elements, with limited or no analysis of the feedback between shoreline management decisions and the impacts...

Clusters of community exposure to coastal flooding hazards based on storm and sea level rise scenarios—implications for adaptation networks in the San Francisco Bay region Clusters of community exposure to coastal flooding hazards based on storm and sea level rise scenarios—implications for adaptation networks in the San Francisco Bay region
Sea level is projected to rise over the coming decades, further increasing the extent of flooding hazards in coastal communities. Efforts to address potential impacts from climate-driven coastal hazards have called for collaboration among communities to strengthen the application of best practices. However, communities currently lack practical tools for identifying potential partner...

Coastal knickpoints and the competition between fluvial and wave-driven erosion on rocky coastlines Coastal knickpoints and the competition between fluvial and wave-driven erosion on rocky coastlines
Active margin coastlines are distinguished by rock erosion that acts in two different directions: waves erode the coast horizontally or landwards, a process that creates sea cliffs; and rivers and streams erode the landscape vertically via channel incision. The relative rates of each process exert a dominant control on coastline morphology. Using a model of river channel incision and sea...
