New Studies Examine Oregon Coast

The Oregon Department of Geology and Mineral Industries (DOGAMI) has released new coastal flood hazard studies for Clatsop, Tillamook, Lincoln and Curry counties.

These studies include detailed hazard zones developed for the open coast using new coastal engineering analyses, decades of ocean wave and water level data, refined modeling approaches, and technology – including use of high-resolution lidar data.

These reports offer state-of-the-art coastal engineering science,” said Jonathan Allan, DOGAMI coastal geomorphologist. “The information is critical not only for further study, but for local, state and federal mitigation planning, risk analysis and disaster response to 1-percent-annual-probability, or 100-year, extreme storm events.”

The work included mapping the geomorphology of the coast, assessing recent and historical patterns of coastal change, field measurements of beaches and bluffs, and new bathymetric surveys of the surf.

Oregon State University investigator Peter Ruggiero, a key technical partner, led the wave modeling and the bathymetric surveying campaigns.

Collection of nearshore bathymetric surveys for much of the Oregon coast also provides an all-new look at the ocean floor from the beach out to depths of approximately 60 feet.

These types of data have never been collected before,” Allan said. “Prior to this the area from the shore out through the surf was a black hole for data in Oregon.”

The detailed science contained in the reports will be used to update regulatory flood insurance rate maps. Specifically, the new analyses reflect updated extreme wave run-up and water level calculations, which ultimately help to guide the determination of Special Flood Hazard Areas (SFHAs) maintained by the Federal Emergency Management Agency.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
