The objective of this study is the development and
verification of an analytical solution for an unsteady
flow field partially occupied by a permeable structure.
Flow is induced by a small amplitude incident wave
train and the permeable structure may contain multilayered
anisotropic but homogeneous material. The analytical
solution developed...
Stabilization structures are the most commonly used form of shore protection along the Oregon coast. Eighty-five percent of the hard stabilization structures built in Oregon
from 1976 – 1999 were riprap revetments. An evaluation was conducted of 143 riprap
revetments in the northern three counties of Oregon. Clear trends exist...
In 1892, the bar at the entrance of Yaquina Bay was 14 feet deep at low tide. Requests to deepen the entrance to 25 feet came from local residents, including supporters of T. Egenton Hogg's Oregon Pacific Railroad, which had its terminus on the bay at Yaquina. The request to...
The United States' declaration of war on Germany on April 6, 1917 imparted some urgency to harbor improvements. This document describes proposed projects at Yaquina Bay: to extend the south jetty, repair and extend the north jetty, construct a spur jetty and dredge the channel. The justification for these improvements...
This is a response for a request for improvement of the Yaquina Bay bar and harbor entrance. Includes information on port and terminal facilities, area industries and commerce, and work done upriver from Yaquina to Elk City. Concludes that further work on the harbor entrance is unjustified.
Reports on a study to consider increasing the depth of the channel at the entrance to Yaquina Bay. Recommends against further channel deepening. "In my opinion it is beyond the power of man to make it into a harbor of sufficient capacity for deep-draft ships engaged in foreign commerce, or...
In 1892, the Senate Committee on Commerce requested the original 1880 survey reports on Yaquina Bay be furnished to them. The 1880 documents are included in this report.
Report to accompany House Resolution 8938. Improvements to the entrance to Yaquina Bay had produced a depth of 14 feet at low water at the bar. Greater depth was desired. This bill authorizes a survey to study the problem and estimate costs of deepening the entrance to the harbor.
