Corporate name TU Delft Date 1965-10-01 Abstract The paper describes a series of tests made in the Columbia River Estuary model at the U. S. Army Engineer Waterways Experiment Station concerning enlargement of the navigation channel at Mi ller Sands Bar. Tests were conducted to determine the effects of enlarging the channel and to determine the effectiveness of various combinations of proposed improvement works. Test results indicated that enlarging the navigation channel from 35x500 ft to 40x600 ft with no improvement works will cause about a 40 percent increase in channel shoaling. Plan 8 was found to be the most effective plan tested. It consisted of six pile dikes spaced 1800 ft apart and placed normal to the predominant flow direction and an 8700-ft dredge fill. The elements of this plan caused a 56 percent reduction of shoaling in the 40x600-ft channel. The paper also describes the purpose of the model study, the prototype, the model, and model testing procedures.
