Abstract

This work uses the separation approach to solve the two-dimensional advection-diffusion problem utilizing the wind speed power law and vertical eddy diffusivity. Comparing data on observed Iodine-135 (I135) concentrations with the proposed, Gaussian, prior studies are done. There more agreements are found between the suggested model and the measured I135 concentrations than between Gaussian and the earlier research.


Keywords: Advection-Diffusion; The Separation Approach; Iodine-135; Gaussian and the Earlier Research.
