Abstract
Diffusion and dispersion in Choba Creek were monitored using modeling and simulation under the influence of velocity. The study monitored the process of arsenic deposition at various discharge stations, where the contaminant was observed depositing different levels of concentration. This implies that the quality of the water in the creek has deposited arsenic as a substance in the environment, and the application of monitoring diffusion rate of arsenic are based on the heterogeneity of the velocity; the study using modeling and simulation were able to express the significant impact of diffusion, because the transport process experienced decrease in concentration with respect to increase in distance for all figures, These conditions imply that velocity in some locations exhibited very low in transport process, which would have resulted in arsenic accumulation in most location, this implies that the rates of concentration would have deposit exponential phase, but diffusion has exhibited higher significant impact compare to dispersion of arsenic. Predicting the Arsenic concentration in Choba Creek has demonstrated the rate of velocity and diffusion impact in the study area; as a result, discharge from some industries has increased the concentration of the contaminant, which this study has monitored the source and the rates of contaminant at different station points. The study is imperative because the contaminant's source has been investigated, the rate of pollution at different point sources has been assessed, and experts will undoubtedly use the transport model as a source for monitoring other creek contaminants, including various heavy metals, in any region of the nation.
