Coastal Engineering and Geomorphology
Coastal communities everywhere are increasingly grappling with the need to balance societal needs, environmental preservation and the growing hazards and risks associated with climate change. Many Alaskan coastal communities are increasingly vulnerable to threats from erosion and flooding. NHC provides strong coastal engineering and geomorphology services crucial for community safety and decision support. With over three decades of experience, NHC’s coastal engineering and geomorphology team specializes in addressing the complex challenges of coastal climate adaptation, particularly in remote northern locations, for both public and private sector clients.
