Abstract
The aspects of heavy-particle diffusion in the tropical estuary is investigated. The two dimensional advection-diffusion equations with tidal and settling velocity were solved with steady state approximation. An analytic solution was obtained in term of Cosines Integral function. The results showed that the profile of concentration follow a tidal cycle with the concentration decrease when the tidal speed is low and increase as the tidal speed is up. On the other hand, at the low speed of tidal current, the pollutants will likely to stay in place.
Key words: Diffusion, estuary, heavy-particle.
