Analysis of the Degradation of Total Petroleum Hydrocarbons (TPH) in a Polluted Stagnant Salt and Fresh Water Environment
Abstract: TPH dispersion in both water media was investigated using a transport model that included convective and diffusion factors. This model was used to track the TPH concentration in both vertical and horizontal dimensions. Therefore, it was expected that diffusion alone would regulate TPH transport or spreading in the x-direction, or horizontal direction, while diffusion and convection caused by gravity would control TPH transport in the vertical direction. As a result, …
