Erosion and Deposition Research and Tools
See below for resources to assess shoreline change and more tools to assist with coastal erosion and deposition.
Northwest Association of Networked Ocean Observing Systems (NANOOS)
NANOOS’ Beach and Shoreline Change Plots is an interactive map which shows multi-season elevation profiles for shorelines along the Pacific Coast of Oregon and Washington.
United States Geological Survey (USGS)
USGS’ National Assessment of Shoreline Change: Historical Shoreline Change Along the Pacific Northwest Coast is a report describing long-term shoreline change, dating back to the 1800s.
Washington State Department of Ecology: Shorelands and Environmental Assistance Program
The Coastal Monitoring and Analysis Program details multiple long-term research projects to assess shoreline change in Washington, along with data and reports for many shorelines experiencing change.
Department of Ecology’s Coastal Atlas contains multi-year aerial shoreline photos, an interactive mapping tool that shows historic shorelines and more.
Preventing Puget Sound Erosion describes shoreline processes, soft shorelines and more. It also hosts an interactive map of soft shoreline projects which combat erosion.
Washington State Department of Natural Resources (DNR)
DNR’s Lidar Portal allows you to see high-resolution elevation maps and download high-resolution data that can assist with managing coastal erosion and deposition.
This list of resources is focused on state-wide information and resources produced by CHRN partners. Contact your city or county planning department for additional local information such as the latest Shoreline Master Program updates, Hazard Mitigation Plans, local maps and more.
