National Assessment of Coastal Change Hazards Active
The National Assessment of Coastal Change Hazards (NACCH) project develops hindcast, real-time, and forecast assessments of the magnitude or probability of coastal landscape change in response to persistent processes (e.g., shoreline change), extreme storms (e.g., Hurricane Sandy), and sea level rise. This effort depends on parallel collection of long- and short-term observations of coastal change, often in response to extreme storm events.
Observation of coastal change drivers, such as wave and water level measurements, are also required and are obtained through CMHRP efforts and via external collaborations. The observations are guided by model requirements for input data and by assessments that predict areas likely to suffer significant coastal landscape change. The models are developed and tested using archived and updated data. Improved data and models are incorporated in updated or revised assessments. For example, the NACCH project responded to Hurricane Sandy with a forecast assessment of coastal change and updated observations.

Forecasting Coastal Change
This project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. The overall objective is to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety.ByNatural Hazards Mission Area, Coastal and Marine Hazards and Resources Program, Pacific Coastal and Marine Science Center, St. Petersburg Coastal and Marine Science Center, Hurricane Dorian, Hurricane Florence, Hurricane Harvey, Hurricane Irma, Hurricane Jose, Hurricane Maria, Hurricane Matthew, Hurricane Michael, Hurricane Nate, Hurricane SandyNational Assessment of Coastal Change Hazards
