About this ebook
The existing Federal project through the Gastineau Channel, Alaska, provides for a navigation channel 4 ft deep at mllw (including overdepth dredging) with a bottom width of 75 ft. The channel was constructed in 1959-60 through an area with a prevailing bottom elevation of +10 to +15 ft mllw and soon experienced rapid shoaling at several locations. No maintenance dreding has been performed, primarily because of the large cost of moving a dredge to this remote area. A model study was conducted to determine the best means of resolving the shoaling problem. The model, constructed to linear scale ratios of 1:500 horizontally and 1:100 vertically, reproduced about 7 miles of Gastineau Channel from Fritz Cove on the west to 1 mile north of Juneau, Alaska, on the east. It was equipped to reproduce and study prototype tides, tidal currents, freshwater inflow, and shoaling. (Author).
