The U.S. west coast is an area of complex coastal geography. This photograph depicts several examples of geological features along the California coastline that are shaped by varied coastal processes. The gently sloping beach, stark bluffs, and presence of smooth rocks suggests that the coastal processes shaping this coastline are complex.

This region of the California coastline is lined with coastal bluffs that have been shaped not only by runoff from rain, but also by wave- and wind-driven erosion. This photo from Pescadero State Beach displays an example of a bluff undergoing erosional processes. Water from the ocean, delivered in waves, can overtop some of these coastal bluffs.

Patrick Barnard explains how the Coastal Storm Modeling System (CoSMoS) integrates information from the Hazards Exposure Reporting and Analytics (HERA) mapper to understand the social and economic consequences of different flooding scenarios.

In collaboration with the Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, the AIM group conducted UAS aerial surveys looking at vegetation classification/index surrounding a MBL gas flux tower located in Nelson Island Creek, Rowley, Massachusetts.

Digital three-dimensional rendering of the coastal cliffs around Point Dume in Malibu, California. Cliff feature outputs from the Cliff Feature Delineation Tool are shown to conceptually display the cliff delineation process, including cross-shore transects (green), the cliff top line (red), the cliff toe line (blue), and subsidiary cliff features (orange).

Map displaying the distribution of total economic losses (direct building damages and indirect economic disruption) in the U.S. that are prevented from flooding by coral reefs annually. In total, the annual coastal flooding risk reduction benefits provided by U.S. coral reefs exceed $1.8 billion.
