In cases where the time scale of interest is long compared with the time scales of the principal energy‐bearing components of water movements, the movement of a soluble contaminant may be represented by a simple diffusion equation with an effective constant horizontal diffusion coefficient, K II . A simple steady state model of the concentration field in the lake of a soluble contaminant introduced on the shore is developed and applied to a situation for which there are appropriate experimental data, the distribution of chloride ion in the central basin of Lake Erie. A horizontal diffusion coefficient, K II , appropriate for basin‐wide diffusion phenomena in the Great Lakes and long time scales may be estimated from experimental data.
