Abstract |
A two-dimensional, stochastic, convective-dispersive transport model was developed to predict expected dilutions for wastes disposed at the 106-Mile Ocean Disposal Site. The major model assumptions were: (1) wastes were completely mixed vertically and remained in the upper mixed layer, (2) the expected center of mass of a discrete dump of material was transported from the disposal site with the mean horizontal current, (3) expected dispersion of a discrete dump of material about its center of mass was determined by the variance and correlation structure of current velocities, and (4) the expected plume from a series of dumps over a period of time can be estimated by superimposing the expected distributions of the individual dumps. |
