Modeling of the Dissolved Oxygen Profile in Marsh Water by Numerical Solution of ADE Using Finite Difference Method

Abstract

To evaluate the environmental impact of pollution, mathematical models play a major role in predicting the pollution level in the regions under consideration. Computer models are becoming increasingly important tools in every environmental management aspects.A general one dimensional water quality model (Advection-diffusion Equation ADE) has been developed the dissolved oxygen in Abu-Zirig marsh water. The general one-dimensional model equation was solved using the numerical solution by finite difference discritization and procedure was prepared by writing a computer program in MATLAB program (version 7.6).
