National Assessment of Coastal Change Hazards
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.
