Projecting climate dependent coastal flood risk with a hybrid statistical dynamical model Projecting climate dependent coastal flood risk with a hybrid statistical dynamical model
Numerical models for tides, storm surge, and wave runup have demonstrated ability to accurately define spatially varying flood surfaces. However these models are typically too computationally expensive to dynamically simulate the full parameter space of future oceanographic, atmospheric, and hydrologic conditions that will constructively compound in the nearshore to cause both extreme...

Drivers of extreme water levels in a large, urban, high-energy coastal estuary – A case study of the San Francisco Bay Drivers of extreme water levels in a large, urban, high-energy coastal estuary – A case study of the San Francisco Bay
Reliable and long-term hindcast data of water levels are essential in quantifying return period and values of extreme water levels. In order to inform design decisions on a local flood control district level, process-based numerical modeling has proven an essential tool to provide the needed temporal and spatial coverage for different extreme value analysis methods. To determine the...

Multiple climate change-driven tipping points for coastal systems Multiple climate change-driven tipping points for coastal systems
As the climate evolves over the next century, the interaction of accelerating sea level rise (SLR) and storms, combined with confining development and infrastructure, will place greater stresses on physical, ecological, and human systems along the ocean-land margin. Many of these valued coastal systems could reach “tipping points,” at which hazard exposure substantially increases and...

Twenty-first-century projections of shoreline change along inlet-interrupted coastlines Twenty-first-century projections of shoreline change along inlet-interrupted coastlines
Sandy coastlines adjacent to tidal inlets are highly dynamic and widespread landforms, where large changes are expected due to climatic and anthropogenic influences. To adequately assess these important changes, both oceanic (e.g., sea-level rise) and terrestrial (e.g., fluvial sediment supply) processes that govern the local sediment budget must be considered. Here, we present novel...

The application of ensemble wave forcing to quantify uncertainty of shoreline change predictions The application of ensemble wave forcing to quantify uncertainty of shoreline change predictions
Reliable predictions and accompanying uncertainty estimates of coastal evolution on decadal to centennial time scales are increasingly sought. So far, most coastal change projections rely on a single, deterministic realization of the unknown future wave climate, often derived from a global climate model. Yet, deterministic projections do not account for the stochastic nature of future...

Assessment of flood forecast products for a coupled tributary-Coastal model Assessment of flood forecast products for a coupled tributary-Coastal model
Compound flooding, resulting from a combination of riverine and coastal processes, is a complex but important hazard to resolve along urbanized shorelines in the vicinity of river mouths. However, inland flooding models rarely consider oceanographic conditions, and vice versa for coastal flood models. Here, we describe the development of an operational, integrated coastal-watershed...
