Abstract

One dimensional advection-diffusion equation is numerically solved by using finite difference method that may be simulated to describe transport of a pollutant in open channel. A generalized Newton Raphson procedure is used to solve the system of equations. The validity of the numerical model is obtained by comparing the experimental results and numerical solution under proper initial and boundary conditions. The spatial variation of concentrations is also compared with the results of experimental measurement. The application of the model revealed good agreement and convincing between experimental and numerical results
