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).
