Abstract : A 1:100-scale model simulating the Ice Harbor Dam project and navigation channel and river downstream from the project was used to test various structural modifications in an attempt to remedy navigation problems which exist as a result of crossflow from the powerhouse. A radio-controlled scale model of a 2000-horsepower towboat with barges was used in evaluating the navigation improvements. Modifications tested included various length and geometric guide wall extensions as well as channel widening. Towboat operators assisted in evaluation of the modifications tested. None of the tested modifications succeeded (to the satisfaction of the tow operators) in correcting the difficulties experienced while navigating downstream from the Ice Harbor lock. (Author)
