Abstract: Results from a series of numerical model runs predicting the short-term fate of dredged material disposed in open water are presented. These results cover a wide range of water depths and ambient currents. The range of conditions tested are intended to represent typical conditions for material to be disposed in Puget Sound. Because the maximum limits material dispersion were of interest, dredged material with a high percentage of readily dispersed clay and silt was used in most of the disposal simulations. General conclusions are that for the typical maintenance material containing both sand and clay/silt , the disposed material will completely deposit within one hour for most conditions tested. The only tests which indicated that a portion of the material remained in suspension after an hour were those in 800 ft of water with currents of 1 knot or greater. In general, the deposition patterns were a function of both depth and ambient currents.
