Simulation of Transport of Pollutants along Kunduchi Beach using Particle models

N. A. Mtega, W. M. Charles


In this article pollutants are released at a certain location in an ideal domain called whirl pool. A particle model is used to describe the dispersion of pollutants in the domain. The diffusion part is modeled by Brownian process and the advection of the particles is mainly contributed by the artificially generated velocity flow fields. In this way, we are able to predict the locations of particles after a certain time since they have been deployed at an initial location and time at time t equals zero. The results of the movement of the pollutants at various locations in two ideal domains are presented in this paper. A point spread function that converts masses of individual particle into concentration is also discussed in this article. Furthermore, the discussion of how to assimilate measurements of concentrations into a numerical model in order to compute accurate predictions of the dispersion of pollutants is also discussed. However, the implementation of the data assimilation is not done in this article yet.
