    • DOGAMI-NANOOS Oregon Beach and Shoreline Mapping Analysis Program

    Metadata Updated: February 27, 2026

    This report describes and documents the Oregon Beach and Shoreline Mapping Analysis Program (OBSMAP) maintained by the Oregon Department of Geology and Mineral Industries (DOGAMI), with funding from the Northwest Association of Networked Ocean Observing System. The objective of this monitoring program is to document the response of Oregon's beaches to both short-term climate variability (e.g., El Ni�os, extreme storms) and longer-term effects associated with the changing climate of the earth (e.g., increasing wave heights, changes to storm tracks, and sea level rise), that will influence the stability or instability of Oregon's beaches over the next century. Understanding the wide range of responses characteristic of the Oregon coast is critical for effectively managing the public beach both today and into the future. Beach monitoring undertaken as part of the OBSMAP effort is based on repeated high-accuracy surveys of selected beach profiles using a Trimble R7/R8 Real-Time Kinematic Differential Global Positioning System (RTK-DGPS) mounted on either a backpack or on an ATV vehicle. The OBSMAP monitoring network currently consists of 211 beach monitoring sites, which include: 6 sites along the Clatsop Plains (Seaside to the mouth of the Columbia River). Monitored seasonally; 25 sites along the Rockaway littoral cell (Cape Meares to Neahkahnie Mountain). Monitored seasonally; 24 sites in the Netarts cell (Cape Lookout to Oceanside). Monitoring dependent on time and funding; 15 sites in the Neskowin cell (Cascade Head to Cape Kiwanda). Monitored seasonally; 33 sites along Gleneden Beach/Siletz Spit (Fishing Rock to Siletz Bay). Monitoring dependent on time and funding; 15 sites in the Beverly Beach cell (Yaquina Head to Otter Rock). Monitoring dependent on time and funding; 58 sites in the Newport littoral cell (Yachats to Yaquina Head). Monitoring dependent on time and funding; 35 sites in the Gold Beach littoral cell (Cape Sebastian to Sisters Rock). Monitoring dependent on time and funding.
